(Universal plug seal) With appropriate spring tension and system fluid pressure, the sealing lip is pushed out and gently pressed against the metal surface to be sealed to form a very good sealing effect. The materials that our company can make include various rubber materials (NBR, FKM, FFKM, SIL, EPDM, HNBR, CI, etc.), various polyurethane materials (oil resistance, hydrolysis resistance, high temperature resistance, food grade, ultra-wear resistance, etc.), various engineering plastics (PTFE, PTFE composite, ultra-high molecular polyethylene, PA, POM, phenolic resin, etc.) and metal materials.

Parameters

The internal open type is suitable for internal positive pressure conditions. The C-ring is a typical self-sealing structure. When the medium pressure enters the C-ring in the working state, the pressure self-tightening effect is generated on the C-ring from the inside to the outside, that is, the greater the system pressure, the better the sealing effect. Due to the principle of opening and self-sealing, it is only necessary to overcome the elasticity of the sealing ring itself during installation, so a very ideal sealing effect can be obtained without using a large pre-tightening force. Our company adopts INCONEL 718 alloy to manufacture.
