SPG

Description

The SPG single-function piston profile is a type of low-friction ring used to save and reduce the occupied space, and it is usually used consecutively to protect and prevent a sudden increase in pressure to the main piston seal. The material used in making this seal is usually PTFE/BZ, PTFE/C and a rubber ring made of NBR. Anti-wear teflon ring has low friction, and by means of special additives, the lifetime of the seal has been increased in long-term working cycles. Also, the teflon ring causes the slip stick effect to disappear.
