High Quality Sterling Made in China

 

The seal is generally composed of a rubber O-ring and a PTFE ring. The O-ring is a force application element, which provides sufficient sealing force and compensates the PTFE ring.

 

It is applicable to the sealing of hydraulic cylinder piston rod. The stem seal is a single acting seal, which is divided into stem seal for piston and stem seal for piston rod. Styroseal has the advantages of low friction, no creeping, small starting force, high pressure resistance, simple groove structure, etc. The latest model is 2K type Steckel seal, which is made of Tecan seal ring and O-ring (nitrile rubber or fluorine rubber).
