A single-acting piston seal operates in the same way as a rod seal, but with one main difference - the dynamic sealing lip of a piston seal is located on the outside.
Double-acting piston seals are designed symmetrically as they are pressurised from both sides. Piston seals are sometimes equipped with pre-loading elements in order to create an even tighter seal. At higher operating pressures, additional support rings are used in order to avoid seal extrusion.
When you’re looking for precision made pistol seals you can count on, you’ve come to the right place. Our seals come in a choice of profiles and materials with different pressure and temperature tolerances as you’ll see in the table below.
