Scope of application
bg

DDMA is used for in-line seals in a variety of liquid applications and is an internal seal. Mainly used for piston and plunger seals. Can be used in mineral oils, modified oils, flame retardant hydraulic oils and compressed air.


DDMA is sealed by a combination of a double-lip elastomer and a wear ring. Before installation, the sealing lip protrudes outward, and after installation, the cylinder liner is pressed tightly to provide elastic force for the wear ring, which can achieve excellent sealing effect even in the absence of pressure. The liquid on both sides of the separable sealing ring is also suitable for the sealing of the oil chamber to prevent the intrusion of other liquids.

Sealing Ring: Filled PTFE

Elastomer: Nitrile NBR or Polyurethane PU
