ED ring is one of the many industrial seals. As aspecial seals for the pneumatic and hydraulic joints, such as pipe joints, hydraulic plugs,and  transition joints etc.it has  better  sealing effect than traditional O-rings.When this elastomeric seal is used as an axial static seal for threaded ports and screw ends.the cross section remains nearly constant under high pressures.Folon.A.as the first one th introduce ED-Ring manufacturing into China,is now the absolute market leader.

Contrast advantages:

The mechanical deformation of the section is small.

There is no relative motion during the pressure cycle.

Long term excellent sealing performance

Working pressure can reach 60Mpa
