Let’s face it – rust happens. Whether it’s equipment that has been exposed to the elements over time or a repair job that someone brings into your shop with frozen, corroded parts. Chains, gears, pipe thread connections, screws, nuts and bolts and all types of metal tools – any of these can build up rust and other deposits from age, misuse or neglect. You need to be able to remove stuck parts to complete a replacement or repair fast. But what is the best way to free rusty nuts and bolts efficiently?Read More

|When it comes to cleaning up after working with paint, oil, grease, tar and other types of tough grime encountered in industrial settings, your hand wash needs to be equally tough. Regular soap isn’t designed to handle oily substances and doesn’t always penetrate the grime left in hands’ creases and crevices. Washing too often, too vigorously, or with cleaners that contain harsh chemicals can dry out and damage skin. Mechanics often develop chronically dry, cracked skin on their hands due to the substances they work with and the amount of washing it takes to remove it. So how do you clean your hands at work but also keep skin healthy and moisturized?|
Parker 7084 Series Twinhammer hose conveys both air to power the jackhammer and water to spray down the work area to supress RCS. Use for compliance wtih OSHA RCS laws.
Use Conversion Kit to upgrade virtually any jackhammer to OSHA compliant tool.
|Since September 2017, OSHA has required the construction industry to comply with new regulations for respirable crystalline silica (RCS) exposure in the workplace. This new standard was enacted to protect workers from airborne silica particles that are generated by grinding, cutting, drilling, sawing and crushing materials such as stone, rock, concrete, brick and mortar. Inhalation of these particles can cause severe health issues including silicosis, lung cancer, COPD and kidney disease. In response, Parker developed the 7084 Series Twinhammer hose and a conversion kit to convert virtually any jackhammer to a tool compliant with OSHA RCS rules.
According to Fluid Power Journal article, "Industry and user experience agree 70% of [hydraulic hose] failures are a direct result of abrasion or external damage—yet many could be prevented."
Hose assemblies that are exposed to regular cycles of heavy friction must be closely monitored for abrasion damage to prevent equipment failure and protect the safety of your workers. Many over-the-sheave applications, such as forklifts, cranes and scissor lifts, need specialized hose shields and covers to protect the hose from abrasion damage. A variety of abrasion resistance solutions are available through Parker to suit specific needs based on the application and work environment. These solutions include abrasion sleeves, protection shields, spiral hose guards and the built-in abrasion resistant hose covers in Parker’s ToughCover, SuperTough and ToughJacket series.
Abrasion sleeves include products such as Parker’s Partek, a lightweight urethane-coated nylon sleeve designed for abrasion resistance and for bundling hose assemblies together. Partek’s unique tubular weave construction allows for the hose to move freely within the sleeve’s exceptionally smooth walls, preventing internal abrasion issues. Partek is available in two versions - Partek “AS”, which is strong enough to withstand over 200,000 abrasion cycles without damage or failure, and Partek “PS”, which can withstand more than 50,000 abrasion cycles. Partek has the advantage of being able to be installed post-assembly, meaning that you can add this product after determining the level of abrasion resistance that your existing hose assembly will need.
For more pinpointed abrasion protection, hose shields provide a low-cost solution for small sections of hose that come into contact with abrasive conditions. The plastic shields are connected with cable ties for easy assembly that does not require disconnecting or removing the hose prior to installation. Hose shields are available in 4, 6 and 8 inch lengths for hose I.D.s of ¼ to 2 inches. Hose shields are not recommended for applications that experience heavy abrasion, particularly if more than just a small segment of the hose assembly is exposed to frequent friction.
Spring Guards & Armor Guards
Parker Spring and Armor Guards can prolong the life of hose assemblies that are exposed to rugged, abrasive conditions. These protective spiral guards are available in a variety of materials and configurations, including clear vinyl, black vinyl, and flat steel. In addition to their abrasion resistant properties, Spring and Armor Guards also prevent hose kinking and provide anti-crush protection.
Parker also offers several polymer spiral wraps that can be added to an existing hose assembly, including the NEXWRAP chafe guard, ParKoil spiral wrap and the PolyGuard heavy-duty hose protector. NEXWRAP can be used to bundle hose, tubing, cables and wiring, protecting the lines from exposure to abrasion. The open spiral design allows for parts of the bundle to be removed without the need to shut down equipment first, preventing downtime. Similarly, the ParKoil polymer spiral wrap can be used to bundle equipment and provides a low-cost solution for abrasion resistance in less-demanding applications. Finally, PolyGuard’s rugged polyethylene cover provides superior abrasion protection and is ideal for bundling high-pressure hose lines.
Abrasion Resistant Hose Covers
For the most demanding applications, built-in abrasion resistant hose covers provide the highest levels of protection. Parker offers multiple hoses in their ToughCover, SuperTough and ToughJacket series – you can find more information on each of these hoses on our new Abrasion Resistant Hose selection page. ToughCover is constructed from synthetic rubber and is 80 times more abrasion resistant when compared to Parker’s Standard rubber cover, SuperTough provides 450 times more resistance, and the ToughJacket series is 650 times more durable and abrasion resistant when compared to standard rubber hose cover.
Which abrasion-resistant hose protection should you choose? The answer depends greatly on your equipment’s specific needs and how much friction the hose assemblies will encounter. For example, in boom and cable track applications, the 563TJ hose is ideal due to its low length change characteristics. The majority of hoses shrink at least 2% in a constricted environment, which can be disastrous in booms and cable tracks as this shrinkage must be prepared for to prevent hoses from pulling out of fittings.
Equipment with over-the-sheave hose assemblies can benefit greatly by selecting a tough cover hose. Forklifts, scissor lifts, bucket lift trucks and reach stackers are just a few industrial applications where hose assemblies encounter numerous cycles of abrasive friction.
Available space can also be a major factor to consider when selecting abrasion protection for your equipment. In tight, constricted spaces or in applications where adding extra weight is a concern, using a hose sleeve or guard may not be practical. Abrasion resistant tough covers can reduce the overall assembly weight and their flexibility allows routing through tight spaces. Alternately, hose guards and wraps may be used if the friction encountered is relatively minor and protection needs to be added to an existing assembly.
Built-In Abrasion Resistance Is Best For:
- Tight spaces where there is not much room for a hose sleeve or guard
- Hose assemblies that need to be as lightweight and compact as possible
- Environments and applications that need the most rugged abrasion protection available
Hose Sleeves/Hose Guards Are Best For:
- Less extreme abrasion where you can save money by using a hose sleeve/guard
- Applications where there are only one or a few points of heavy abrasion that need to be protected
- Hose assemblies where you may need to remove the abrasion resistant hose guard/sleeve, or want to add it to an existing assembly
Factors like fluctuating or inexperienced personnel, shortage of skilled workers and increasingly difficult installation conditions can lead to tube assemblies being incorrectly installed. The results are leaks, costly downtime and inefficiency, as well as increased safety risks. Driven by the customer desire for simplified fitting technology, Parker developed the innovativeEO-3® flareless fitting system. Utilizing a special tapered thread and visual status recognition, it speeds tube assembly and improves assembly accuracy.Read More
The U.S. Occupational Health and Safety Administration (OSHA) has created a new standard to address the problem of crystalline silica dust control associated with pneumatic jackhammer and breaker operation in the construction industry. The mandated compliance date of the new silica rule has been postponed to September 23, 2017.
In reaction to this new rule, Parker has developed the 7084 Series Twinhammer™, an air-water jackhammer hose which helps companies comply with OSHA's crystalline silica dust control guidelines. Unlike other silica dust suppression systems, Twinhammer™ assemblies are constructed as a unitized, low-maintenance solution that can be easily integrated into construction applications affected by this rule.
In many automated manufacturing applications, assessing potential safety risks posed by unexpected power failure is an essential part of overall system design. You need to take appropriate measures in order to reduce the risk of injury to machinery operators and other personnel, and prevent damage to the products being assembled. In the case of any kind of unexpected interruption in operation, the equipment must meet safety standards that prevent unsafe situations from occurring.Read More
