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.
Bore-Sealing Spring-Loaded Rotary Shaft Seals with Wiper Lip



Ribbed Buna-N over steel creates a tight seal with the bore, even when mating with a rough surface or in a split housing. Also known as oil seals, these retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. They have a secondary lip that blocks contaminants and a spring that secures the sealing-lip to prevent leaks. Press-fit seals into the bore around the shaft. Seals with a maximum pressure of 145 psi should be secured with a retaining ring.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip against the shaft, preventing messy leaks. Press-fit seals into the bore around the shaft.
Seals with an acrylic-coated case have a coating that compensates for surface imperfections in the housing bore for a tight seal on the OD.

Rotary Shaft Seals for Grease



Also known as grease seals, these are designed to retain thick lubricant at low pressure in motors, pumps, bearings, and gearboxes. They have a light grip on the shaft that creates less friction than spring-loaded seals. Press-fit seals into the bore around the shaft.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Shaft-Mounted Rotary Seals
Also known as V-rings and flingers, these seals protect shaft bearings by blocking dust and other contaminants while retaining lubricant. They’re Buna-N for excellent resistance to oil and grease. To install, stretch the seal over your shaft and press it firmly against the face plate. The Seal ID, OD, and Width listed are the dimensions of the seal after it is installed.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Mechanical Pump Shaft Seals with Extended Spring

For use in waste water, boiler feed, and compressor pumps, these seals have an extra-long spring that accommodates variations in seal cavity length. They come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. The seat is comprised of the seat and the gasket.
Buna-N diaphragms and gaskets resist grease and a wide range of oils.
Viton® fluoroelastomer diaphragms and gaskets resist a wider range of chemicals than Buna-N.
EPDM diaphragms are more resistant to water and steam than Buna-N and Viton® fluoroelastomer, but aren’t as resistant to oils and chemicals.
Carbon washers are for use with clean liquids.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

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.
