CQB type
Piston seals
Features
Type CQB is an optimized seal on the structure of Type CQA. The internal use of two O-rings as the force element optimizes the pressure distribution and reduces the destructive force of the gas on the seal. The characteristics of low friction, high pressure resistance and high speed of PTFE seals are preserved, as well as the characteristics of rubber seals. It is suitable for occasions where the speed is high, the pressure is high, and pressure maintenance is required.
Material
a) Sealing ring
