ED ring is a kind of industrial seals, as pipe joints, hydraulic plugs, transition joints, and other pneumatic and hydraulic special seals, the sealing effect is better than traditional O-rings.
This kind of elastic seal is used as an axial static seal, using re-threaded oil port and screw end, the cross-section remains almost constant under high pressure.
Advantages: the mechanical deformation of the section is small; there is no relative movement during the pressure cycle; the excellent sealing performance is maintained for a long time; the working pressure can reach 60MPa,and the material is diversified;
