Double acting piston seals

Double acting piston seals

Piston seals designed for bidirectional pressure
The best sealing capacity of a double-acting cylinder, capable of sealing dynamic pressure from both sides (bidirectional), is achieved by choosing a double-acting seal.

A piston design where two single-acting seals on the piston for a double-acting cylinder are used can easily give rise to a breakdown. The reason is that a very high pressure can be trapped between the seals.

Piston seals, both single and double-acting, can be designed for and used with integrated or separate back-up rings and guide rings.
