In a previous blog from January 2014, Don’t Kill Your Pneumatic System With Bad Air, we wrote about how water, dirt and oil contamination can damage your machine and cause it to run inefficiently. Rust, dust and other impurities can clog air systems and contribute to premature wear and tear on seals and other components. To provide the purest air quality possible, a combination of filters should be connected to the air-flow to capture these impurities before they contaminate the system. However, each compressed air system has unique needs – what may be right for one system may not be the correct choice for another application, when considering environmental factors or fitting a system into a tight space.Read More

Hose and coupling connection is critical to the safe performance of any hose assembly, but the practice of using hose and couplings from different manufacturers to fabricate industrial hose assemblies poses some underappreciated risks.Read More
When people talk about oil spills, the first image to come to mind is often the large-scale disasters involving oil rigs, oil pipelines or derailed trains. Barrels of oil saturating the soil or dumped into a body of water, with devastating effects on the environment– this is a worst-case scenario come to life. The cost of a major spill, in dollars, man hours and damage to a company’s reputation, can be enormous. What you may not realize, however, is that spill containment on a smaller scale can be very costly as well.Read More
Many scenarios like this one can be prevented with the right monitoring equipment. The ability to take frequent readings of pressure, temperature and humidity can make all the difference when it comes to keeping your equipment running at top performance. Parker’s SensoNODE™ advanced monitoring system provides immediate access to accurate readings of your most vital equipment’s condition, allowing you to identify any potentially damaging changes before a failure occurs.
It’s one of any company’s worst nightmares. A key component of your equipment has failed and production has halted. You determine that the part failed due to overheating or an unforeseen spike in pressure. Whatever the reason, your company loses revenue for as long as the downtime continues – not to mention the inevitable cost of repairs.
Parker’s 5CNG Compressed Natural Gas Hose will be on display at ACTEXPO 2015 in Dallas, Texas, May 5-8, in Parker booth number 537.
Parker’s Fluid System Connectors Division (FSC) is implementing a conversion of FC701 and FC702 flow controls in fractional sizes. Replacement options for FC701 are Parker/Legris FCM 731, FCC731, and FC705. The replacement option for FC702 is FC708.
In July 2010, we published an article about the importance of what's on the layline of a hydraulic hose - and how to interpret it. Here it is again, this time with a video from Parker Hannifin:

In our earlier blog, Early Warnings of Hydraulic System Troubles, we introduced the Parker SensoControl family of diagnostic tools. SensoControl diagnostic tools are designed to help hydraulic system maintenance professionals identify sources of slow operation, increased noise, and elevated temperature. This January, Parker announced a new enhancement to their ServiceJunior product - the color-coded cover.
Dwelling in the compressed air, which runs your machines, are three ingredients that will guarantee the slow destruction of your machines:
New Protection from High Pressure Hose Assembly Blow Out
Parker Partek Defense is a new hose sleeve which can help prevent injuries from a blown-out hose by containing, and then dissipating, the energy and media within the hose assembly.
There are many ways that people get hurt around hydraulic equipment as a result of a hose blow-out.
Injuries include hot oil burns, slipping on oil spills, bruises, cuts and broken bones from hoses that whip around wildly. The frequency of these types of injuries can be greatly reduced by sound safety and maintenance policies, and by being smart about high-pressure hose routing.
Partek Defense Protective Hose Sleeve
There is a new safety product which can help prevent a blown-off hose from causing injuries – a special protective hose sleeve called the Partek Defense. In the past, hose whip restraint systems did not address the high pressure fluid containment. The Partek Defense hose sleeve not only prevents hose whip, it also prevents hot hydraulic oil from spraying over a large area.
How Partek Defense Hose Sleeve Works
Partek Defense is designed to provide protection to personnel and equipment in the event of a hose burst by containing the energy of the burst. It features a multi-layered construction that contains and then dissipates the energy and media within the hose assembly. It can be applied to any hose application, but is most valuable in industries such as mining, construction, and agriculture where operators are in close proximity to high-pressure hoses. Partek Defense provides burst protection up to 12,000 psi.
Partek Defense is flexible so it does not restrict hose movement and does not limit the hose routing options. It is made from high-strength coated fibers which hold up against ultra-violet light, ozone, and other environmental elements. Partek Defense is approved for use with Parker 43, 70, 71, 73, 77, 78, and 79 Series fittings. It’s available in 50-ft lengths.
Installation Instructions for Partek Defense
- Determine the size of the Partek Defense Sleeve to be used – use the chart below.
- Cut off a length of Partek Defense Sleeve equal to the overall length of your hose assembly.
- Slide the sleeve over the hose assembly.
- Secure the end of the sleeve to the hose fitting shell using a metal band clamp (P/N: FSC), and the FSC Clamp Tool (P/N: FST-711617).
At this point it is not clear if the Partek Defense protects against hose whip if a fitting completely blows off the hose. This question has been posed to Parker Hose Division engineers and will be posted when an answer is received.

Other Safety Measures Regarding Hose Blow-Outs
There are also various safety tips posted on the safety of hydraulic systems – here are links to these related, earlier blogs:
- Know when to replace the hose assembly – Preventive maintenance, including replacing hose assemblies close to their service life, goes a long way towards preventing blow-outs in the first place.
- 7 Most Common Crimping Mistakes – Without a doubt, the most common cause of a premature hose failure is incorrect assembly.
- Electrical Properties of Rubber Hose – This is a frequently overlooked aspect of hose selection, but ignoring it has the potential for real disaster.

To address the common challenges of choosing a replacement coolant or return line hose, ask these questions:
Early Warnings of Hydraulic System Troubles:
- Slow Operation
- Increased Noise
- Elevated Temperature
Longer cycle times are often the first indication that there is something wrong with a hydraulic system. Decreased speed of hydraulic actuators (such as cylinders) points to decreased flow through the system.
1. PVC Pipe
|The use of PVC pipe is common but NOT RECOMMENDED for use with compressed air. It is often used because it is readily available, inexpensive, and easy to install. However, as with many plastics, PVC gets brittle over time and can crack, break, or even shatter. The presence of air compressor oils in the line and heat from the compressed air accelerates the degradation of PVC. These failures, combined with air under pressure, are potentially fatal due to the airborne, razor-sharp shrapnel. It is also an OSHA violation to use PVC for compressed air distribution, which means you could incur a hefty fine.|
2. Galvanized Pipe
|Galvanized piping is commonly used for water distribution and for general plumbing. Galvanized coating resists moisture in compressed air but pieces of the coating will flake off and end up in your tools. The debris will cause severe damage to cylinders, pneumatic tools, and other components. Even more importantly, when exiting a blow gun, little flakes can cause serious bodily harm. Galvanized piping is NOT RECOMMENDED for compressed air systems.|
3. Black Pipe
|Black pipe is the most commonly used pipe RECOMMENDED for compressed air systems. It is readily available, it is strong and durable and most people are familiar with how to install it. With all of the advantages black pipe provides, however, it will produce rust contamination that damages pneumatic tooling. The pipe is uncoated, and the presence of moisture will initiate rusting which will increase over time. The presence of moisture can be controlled with an after cooler and/or dryer, but it can never be completely eliminated. Furthermore, the installation of black pipe systems requires significant amount of time. Plan carefully, changes to the system will require de-pressurizing the system while new drops or additional loops are added.|
4. Copper Pipe
|Copper pipe is commonly RECOMMENDED for clean air, it works very well, and it is expensive. Copper pipe makes for an aesthetically pleasing installation, but the soldering of joints is time consuming and requires skill. Since the combination of copper and water does not create any corrosion or rusting, the air delivered to the pneumatic tools is clean and free of particulates.|
5. Stainless Steel
|The RECOMMENDED use of stainless steel to minimize corrosion has a long and successful history. It combines all of the strength and durability benefits of black pipe, but without the problem of rusting. As with black pipe, most people are familiar with how to install the fittings and pipe, but the installation is a lengthy process. Stainless Steel pipe threads also have a tendency to gall and freeze up which can cause great difficulty during disassembly, and for general maintenance. For this reason, Victaulic fittings have successfully been used. Victaulic fittings are installed with a rubber seal and bolted clamp. Victaulic fittings are the preferred fittings for larger pipes, whether black or stainless steel, due to their lighter weight.|
6. Aluminum Pipe
|The latest technology are push-to-connect aluminum piping systems for compressed air lines (such as Parker Transair). Aluminum is light-weight, making it easy to handle compared to schedule 40 or 80 pipe, and is HIGHLY RECOMMENDED for clean air applications. It is non-corrosive, as is the copper pipe, and will deliver clean air to the pneumatic tooling. The Parker Transair brand of aluminum piping uses push-to-connect fittings, which make installation fast and easy. Skilled labor is not required to install TransAir.|
|The new Parker Tracking System (PTS) makes it fast and easy to replace hose assemblies previously purchased at any participating ParkerStore location. The PTS is designed to help reduce downtime by increasing the speed, timing, and accuracy of replacing customers’ hose assemblies. This can provide critical machine uptime, and enable a more conveniently scheduled repair.|

Does this sound familiar?
- Your hose is exposed to temperatures below -50°F or above +300°F.
- Your hose’s cover is cracking.
- Your hose is exposed to harsh chemicals.
- You keep replacing the same hose over and over.
- You wish you could use a metal (rigid) tube, but you need the flexibility of a hose.
If this is you, stop replacing the same hose over and over – go for a flexible metal hose!
What You Don't Know About Hoses Can Kill You...Because electrical conductivity or non-conductivity is not a consideration for many applications, hose manufacturers do not commonly publicize hose electrical resistance ratings. That being the case, most people do not think about conductivity when selecting a hose; some just assume that all rubber hoses are electrically non-conductive. After all, rubber is non-conductive material, right? Wrong.

Did you know that over 100 million gallons of hydraulic fluid are lost each year due to preventable leaks?Hydraulic leaks cost many companies a lot of money in man-hours to find and fix the repairs, replacement hydraulic oil, and machine down-time. Hydraulic fluid leaks can also lead to possible EPA (Environmental Protection Agency) monetary fines or, worse yet, plant closures. Most hydraulic leaks occur at threaded connections. The following are causes of, and tips to prevent, leaks:
The first step in preventing a hydraulic fluid leak is in design:
- Design a system with as few joint or thread connections as possible.
- Properly support the tubes, pipes and hoses conveying the hydraulic fluid. Vibration could result in joint or connection failure.
Poor repair and maintenance practices can also contribute to leaks in the system:
O-ring failure could be the cause of leakage.
- Make sure the O-ring material is compatible with the media being conveyed
- Make sure the O-ring material is rated for the expected temperature range
- Make sure the O-ring did not get pinched during installation
Improper connection assembly is another common source of hydraulic leaks:
- Over-tightening a JIC connection
- Using a 45° flare tube nut instead of a 37° flare in JIC tube end connections
- Missing sleeve on JIC or SAE flare tube connections
- Missing, or incorrectly applied, thread sealant on pipe threads
- Bite not preset correctly in a bite-type connection
