By Josh Cosford, Contributing Editor Hydraulic fittings and couplings get taken for granted, especially with mobile machinery, where profit margin can overshadow design. The reality is that fittings and couplers are as crucial to the design of a machine as are the pumps, valves and actuators. Let’s consider what makes a hydraulic fitting functional: it […]

Machine builders and maintenance technicians must ensure that hoses are properly secured to the correct connection. Unfortunately, when dealing with multiple hoses on a complicated machine, personnel can waste a lot of time just identifying the proper routing and mating ends. Worse, there can be equipment damage due to incorrect connections or, in the case […]

I recently chatted with Michael Haen, VP of Global Product Line Management, Fluid Power, for Gates Corp. about what’s new at the manufacturer of hydraulic hose assemblies and what they see is coming on the horizon in terms of technical updates. Mary Gannon: You just did a big expansion of your PRO series. Tell us […]

Hydrodynamic torque transmission of fluid couplings protects belts, motors and drives. Contributed by Kyle Kluttz, Director of Mining and Minerals Div., Voith Turbo, York, Pennsylvania Conveyors used in surface and underground mines, mineral-processing facilities, harbors and ports routinely move hundreds if not thousands of tons per day. The growing worldwide demand for natural resources has…

Hydraulic and pneumatic hose safety can be ensured by using quick-connect fittings or quick couplings that make a repeated connection and disconnection between fluid lines and the equipment they are attached to. Quick couplings are used in both hydraulic and pneumatic applications, and are designed for easy hand operation. These safety devices feature a male […]

Hydraulic quick-coupling manufacturer Stucchi Inc., with U.S. headquarters in Romeoville, Ill., is launching a new series of heavy-duty locking quick-connect couplings at ConExpo/IFPE 2017. The VEPHDL locking thread-to-connect coupling system reportedly ensures safety, improves efficiency, eliminates environmental issues and increases productivity for the most demanding hydraulic applications. Scott Rolston, President of Stucchi Inc., said, “We…

Although not one of the most common fittings used in fluid power applications, brass fittings are extremely useful in corrosive environments for both hydraulic and pneumatic hose and tubing applications. Anderson Metals offers a variety of fittings, including 45° flare fittings, pipe fittings, and push-on hose barbs for a wide range of temperatures. The SAE 45° flare […]

Before you select a hydraulic fitting, you must first determine if its threads will match the hose you have selected. Measuring and identifying the fittings is easily done but you must have the correct tools. These tools include ID/OD calipers and thread pitch gauges. Using the thread pitch gauge, as seen in Figure 1, simply […]

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 […]
