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.
Head 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.

Rod-Sealing Wipers
A two-lip design means that these wipers also function as a rod seal.
Wipers that meet ISO 6195 Type C fit grooves with the dimensions and tolerances specified by the standard.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Rod Wipers for Open Grooves
Replace wipers in open-groove cylinders—these wipers have an integral steel case that press fits into the groove around the rod.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
