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.
Blog - Hose & Fittings, Etc.
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:
If you are using Parker 55 series, 58 series or 58H series fittings, read this!
Parker Parflex’s new 56 series fittings are replacing the Parflex 55 series and Parflex 58 series fittings. 56 series fittings are now available in all sizes except, sizes -10,-12 and -16 (5/8”, 3/4” and 1-0”) bent tube fittings. Parker is expected to release those between May 1 and July 1, 2014.

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.

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.|
