PG3

PG3 Piston Seals' high-strength seal ring material prevents seal extrusion allowing this seal to be used in elevated operating pressure applications. It also offers excellent wear resistance and a wide operating temperature range. The PG3 seal design includes a built-in fluid reservoir between the sealing lips to retain lubrication, which lowers the break-out and running friction and ensures extended seal life. 

The PG3 series piston seal is designed to retrofit standard North American housing standard (NFPA T3.19.18), which is commonly referenced as a rectangular piston seal.

The PG3 Piston Seal has been redesigned to the PG7 Piston Seal. Click here for more information.
