Compared with rubber oil seals, PTFE oil seals have more advantages
Compared with rubber oil seals, PTFE oil seals have more advantages 1. The rubber oil seal adopts a sharp lip that is compressed by a spring, and the contact surface with the shaft is only 0.3-0.5mm wide. The PTFE oil seal adopts a spring-free wide lip dynamic structure, and the contact surface w...Read more -
How to improve the purity and wear resistance of PTFE gaskets
PTFE gaskets are flat gaskets, V-shaped gaskets, piston rings, ball valve gaskets made of PTFE rods, tubes, and plates by mechanical turning or cutting. They have excellent corrosion resistance, anti-aging and non-conductivity. characteristic. So, how to improve the purity and wear resistance of ...Read more -
