Contributed by Xing Hong, Founder, WRKR Seal Hydraulic systems depend on reliable sealing at every connection point. When an O-ring fails in a hydraulic circuit, the consequences range from minor fluid weeping to catastrophic pressure loss, environmental contamination, and unplanned downtime that costs thousands of dollars per hour in heavy industry. Yet a significant share […]

Keeping contamination at bay and protecting cylinders in mining applications requires careful selection of hydraulic seals. By Josh Cosford, Contributing Editor Let’s just cut to the chase; mining makes for a horrific environment for seals. From incessant contamination to pressure spikes, and from exotic fluids to environmental extremes, pretty much every cause of hydraulic seal…

By Josh Cosford, Contributing Editor Seals are often an afterthought when it comes to designing fluid power systems, which makes sense for the majority of applications where off-the-shelf is good enough. Designers select pumps, valves, and actuators based on criteria like flow rates, valve configurations, and pressure capacities, but most of those primary components are […]

By Josh Cosford, Contributing Editor Here at Higginson Equipment, we produce a line of cylinders for the dump truck industry known as EconoMAX. On any given year, we produce between 7,000 and 8,000 of these for tailgate latch, air tarp systems, and tailgate high-lift applications. Each cylinder contains a T-seal for the piston, two end […]

By Josh Cosford, Contributing Editor Let’s start by stating the obvious: seal geometries matter, or the fluid power realm would use only geometrically simple O-rings. The other two critical factors for effective seal performance are polymer composition and a machined groove to call home. However, even considering the latter, a seal geometry of the same […]

By Josh Cosford, Contributing Editor Sometimes, there’s a practical and propitious device that’s been around forever, only to be discovered by happenchance, yet it provides immense value and serendipity. I have been known to use hyperbole in my writing, and maybe so here. Still, if this article convinces just one reader to use this simple […]

By Josh Cosford, Contributing Editor When buying a cylinder repair kit, you generally expect to open a plastic bag filled with O-rings, rod seals, end seals and other synthetic rubber bits used to freshen up an old air or hydraulic cylinder. Often, we call such an assembly of parts a seal kit, which completely forsakes […]

By Josh Cosford, Contributing Editor Seals used for fluid power applications are highly varied and specific to each component and application. From simply sealing pressurized air from atmospheric air for pneumatic valves to preventing hydraulic oil from leaking into waterways from the rudder cylinder on watercraft, there are few conditions in which a fluid power […]

Will hydraulics ever get past the leakage issue? I’ve heard people discuss this question countless times over the three decades that I’ve worked in and written about the technology. Time and time again, people bash this useful technology because of perceived problems with leakage. I have encountered this negative talk on factory floors, in educational…
