New to the Stauff Connect product range and introduced for the first time at the Hanover Fair are FI-WDDS-type soft-sealing cutting rings, which compensate for settling effects in tube fittings, for example, from temperature fluctuations or from pressure pulse and vibration loads in a hydraulic system. With 24° tube connectors, 37° flared tube fittings and […]
How do you protect hydraulic hose?
Hydraulic hose assemblies rarely operate in controlled, protected environments. Rather, rough and demanding conditions are the norm. Thus, hose is often exposed to flying debris in mobile equipment and the likes of weld spatter and hot metal chips—or even the errant lift truck—in industrial settings. Add to that, hoses subjected to continuous movement and machine […]
What is nonconductive hose?
Engineers and technicians specifying hoses for hydraulic circuits routinely consider factors like pressure ratings and flow capacity. But in some instances, electrical shock is a potential risk to equipment and operators, and that demands hydraulic hoses that ensure safety when machines operate near high-voltage sources like power lines. Thus, nonconductive hydraulic hoses are recommended for […]
What is a thermoplastic hydraulic hose?
Thermoplastic hoses are common in both mobile and industrial equipment, and they are widely used in medium-to-high pressure hydraulic applications. Related products are often specified for handling compressed air and other gases, transporting chemicals, and in water-cleaning and paint-spray operations. Like its rubber counterpart, thermoplastic hydraulic hose typically has an inner tube, one or more […]
What is rubber hydraulic hose?
Rubber hydraulic hose is a common and important element in countless industrial and mobile machines. It serves as the plumbing that routes hydraulic fluid between tanks, pumps, valves, cylinders and other fluid-power components. Plus, hose is generally straightforward to route and install, and it absorbs vibration and dampens noise. Hose assemblies—hose with couplings attached to […]
How does extreme heat affect hydraulic hose?
In a previous posting, the editors at Fluid Power World discussed how ultra-low temperatures can play havoc with the performance of typical rubber hose. Hydraulic hose used at high temperatures faces performance issues too, but for different reasons. That’s because thermal exposure can cause aging of elastomers and plastics. (Other causes of aging include exposure […]
5,000-psi coupling connects by hand
In underground mines, traditional staple-lock hydraulic couplings take a beating. They often get abused and damaged, and that makes them difficult to disconnect and service. At this year’s MINExpo show in Las Vegas, experts from Gates Corp., Denver, explained how their iLok coupling addresses the shortcomings of traditional staple-type connections, providing sizeable savings in assembly […]
Stud welder speeds hose and tube clamping
Stauff recently introduced a stud-welding system that simplifies the installation of clamps for hose, tubing, pipe and cable. The SWG Stud Welding System reportedly provides a fast and easy way to attach threaded studs to a machine or structure. The studs replace conventional weld plates, and are the base for mounting the company’s standard hose […]
Hydraulic-injection injuries prevented by Fluid Power Glove
Pirtek Europe, based in London, has developed the Fluid Power Glove, a safety glove specifically designed to prevent painful and debilitating hydraulic-injection injuries to the hand. The root cause of fluid-injection injuries is pin-hole leaks in high-pressure hose that generate a needle-like spray of high-velocity oil. In fact, the velocity of fluid forced through a […]
Safety guidelines for high-pressure hydraulics
Handling high-pressure hydraulics is serious business. It often involves working in confined spaces, lifting heavy machine parts or dealing with weather extremes in remote locations. This has led to a demand for smaller and lighter tools to simplify tasks. But that necessitates higher pressure to generate sufficient force or torque. To make engineers and maintenance […]
