ROD SEALS

PTFE rod seals: single- and double-acting

Rod seals are dynamically active on the inside diameter. (view piston seals here)

Single acting:
The single-acting seal is designed to function where pressure is only applied from one side.

Double acting:
A double acting seal has the benefit that it is the most compact way to design a reliable sealing system, when pressure is applied from two sides.
