Internal pressure metal E-type sealing ring (E-type inner opening)
Product Description
Metal E-ring seals are an important part of engines and are mainly used in aerospace, steam turbine and automotive industries.
"Compared with O-shaped, C-shaped, U-shaped and other metal sealing rings, its advantages lie in the small compression load required for installation, good resilience (close to 100% rebound at room temperature), and can be used under high temperature, high pressure and vibration. It is used in the working environment. During use, the E-type inner opening is suitable for internal pressure conditions, and the E-type outer opening is suitable for external pressure conditions. "The system pressure increases the adhesion between the sealing surface and the flange (self- tight function), thereby greatly reducing the leakage rate.
