Valve Stem U-Packing Seals

The packing material made of rubber is combined with the vulcanization of the shell made of PTFE, and the rubber is the main pressure bearing element.

The interference of the inner and outer diameter ensures that the shell is close to the sealing contact surface, so as to realize the sealing principle.

It is often used in medium pressure valves with good leakproof performance. As a low-cost valve stem seal is widely used in the petrochemical industry.
