About Cylinder Seals
Rod wipers scrape dirt, dust, and moisture from the rod, preventing contamination inside your cylinder.
Rod seals maintain the pressure inside cylinders and prevent fluid from leaking out.
Wear rings guide the rod and piston to prevent uneven wear and optimize seal performance.
Head seals are a more reliable alternative to the standard O-ring/backup ring combination—they resist twisting and remain stable even in applications with fluctuating pressure.
Buffering seals protect hydraulic cylinders from pressure spikes and shock in high-pressure hydraulic applications.
Cushioning seals minimize wear and noise in air-powered cylinders by preventing the piston from slamming against the cylinder body.
Piston seals make a seal between their outside edge and the cylinder bore to prevent internal leaks.
Ultra-Chemical-Resistant Kalrez 4079 O-Rings
Inherently softer and more compressible than PTFE O-rings, these Kalrez 4079 O-rings have comparable chemical resistance. Use them with acetone, methyl ethyl ketone (MEK), potassium hydroxide, and most acids. They have a round profile and are suitable for a wide range of static and dynamic sealing applications.
Metric O-rings are sized to the actual measured inside diameter.

High-Speed Wear Rings
Profile
Piston Installation
Rod Installation
Made from PTFE, these wear rings have a slippery surface that allows rods to move at least three times faster than nylon wear rings.
Gap size is the maximum distance between the split ends of the ring while it is in use. Rings are closed when not in use.
