Pneumatic seals operate typically in air or other gaseous medium.

Symmetrical Seals are seals whose cross section, when viewed from a cutaway, is symmetrical, i.e., the same on each side of the center line (see below). These seals are for linear and reciprocating dynamic applications.

The symmetrical design allows for interchangeability between rod and piston applications. These type of seals became very popular because of their great advantages for reduced inventory and stock keeping purposes.

If, however, you require the best sealing results and durability, we recommend you select one of our rod or piston seals, depending on your application. These seals have very specific design features which deliver better results than Symmetrical Seals.
