Spring sealing ring

The Pan Plug Seal is a U-shaped Teflon high-performance seal with a special spring inside. By the appropriate spring force plus the system fluid pressure, the sealing lip (surface) is pushed out and lightly pressed against the sealed metal surface to generate a very good sealing effect. The actuation effect of the spring can overcome the slight eccentricity of the metal mating surface and the wear of the sealing lip, while maintaining the expected sealing performance continuously.

Teflon (PTFE) is a sealing material with better chemical resistance than perfluoroelastomer and good heat resistance. It can be applied to most chemical fluids, solvents, hydraulic oils and lubricating oils. Its swellability is very small, so it can exert its sealing performance for a long time. Various special springs are used to overcome the elasticity problem of Teflon or other high-performance rubber and plastics. ) Seals, the temperature range can be from refrigerant to 300℃, the pressure can be from vacuum to ultra-high pressure 700kg, the moving speed can reach 20m/s, and the spring can be made of stainless steel, Elgiloy Hastelloy, etc. according to different use environments, so it can be applied to various for high temperature corrosive fluids.
