Piston Seals

Pneumatic piston seals

Whether you need seals for basic applications or for high-temperature abrasive environments, our seals are designed to provide successful service. Having been in the industry for several decades, we know the seal designs and materials that work best. Our seals demonstrate excellent wear resistance in pneumatic cylinders and valves. They are designed for lower operating pressures than hydraulic seals, and are suitable for use in rotary as well as reciprocating motion.

Hydraulic piston seals

When you need unfailing protection in your heavy-duty hydraulic applications, look no further than Valley Seal for the best products on the market. We carry a special range of seals designed especially for use in hydraulic applications subjected to high pressures and temperatures. Valley Seal offers the industry-trusted OK sealing assembly that is suitable for working pressures up to 7250 PSI (500 bar) and above in some specific situations. The Piston Seals OK Profile is an effective and less expensive alternative to costly capped T-Seals and PTFE loaded cap seals. We can also honor your unique seal requirements for pneumatic and hydraulic fluid sealing applications.
