The back support ring is a kind of sealing spare parts used for machinery, equipment and pipelines as long as there is fluid. It uses internal and external materials to seal. The back support ring can be designed and manufactured for the air pump seal of the automobile. In order to meet the requirements of the working environment of the air pump of the automobile, the polytetrafluoroethylene (PTFE) raw material is proportioned, and the performance of the polytetrafluoroethylene (PTFE) raw material is improved. After inspection and testing, the temperature range of the backing ring seal is extended from 200 degrees Celsius to 260 degrees Celsius, which greatly improves the performance of the backing ring seal ring in the car air pump.

PTFE seal products to meet the needs of customers, seals products have a long service life, reduce the number of disassembly and assembly of machinery due to leakage problems, save machine loss for customers, extend machine life, Guangdong Teflon back support ring manufacturers High efficiency has been well received by many customers. High-quality seal products determine the working efficiency of the machine. Choosing a good sealing ring can reduce mechanical failure, ensure efficiency and make the machine last longer. This series of products has excellent high temperature resistance, wear resistance, corrosion resistance, aging resistance, flame retardancy, excellent dielectric properties and self-lubricating characteristics. At the same time, according to the requirements of product pressure, temperature, insulation, chemical resistance and wear resistance, each material is filled with different materials or parts.
