Also known as loaded-lip seals and PolyPaks, an O-ring secures these U-cups to the rod or piston for better sealing performance at lower pressures than unsupported U-cup seals.

In addition to providing excellent sealing performance at low pressure, these seals withstand a wider range of temperatures and chemicals than U-cup seals. They’re also known as spring-energized seals.

A square O-ring prevents these piston seals from rocking in the groove.

Avoid common O-ring failure in dynamic applications—the square base of these seals prevents twisting, while backup rings protect against extrusion.

The slippery PTFE surface of these seals allows rod motion up to seven times faster than our other rod seals.

Replace the standard O-ring/backup ring combination with a more reliable alternative—these head seals resist twisting and remain stable even in applications with fluctuating pressure.

These rod wipers are also known as U-type wipers.

Replace wipers in open-groove cylinders—these wipers have an integral steel case so they press fit into the groove around the rod.

Cut this stock to make wear rings that fit any rod or bore diameter.

Made to fit the most common mounting footprint, these cylinders have an NFPA (National Fluid Power Association) industry-standard footprint, ensuring easy interchangeability.

Cylinders have two parallel piston rods that prevent twisting as they extend and retract.

Threaded through-holes in each corner allow you to mount these cylinders directly to equipment or mount with attachments.
