Combination gaskets are suitable for pipeline systems with oil as the medium, for welding, threaded pipe joints, ferrules, expanded pipe joints, screw plugs and mechanical device sealing systems, mainly suitable for end face static sealing of hydraulic valve pipe joint threaded joints , It is made of rubber ring and metal ring integrally bonded and vulcanized to prevent leakage of oil, fuel, water and medicine. Because of its simple structure, efficient sealing, and low price, it is widely used in the machinery manufacturing industry. 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.
