Compact Seal-DDAS

(5-piece seal) Type DAS Compact Seal

The internal sealing element is made of nitrile rubber (NBR) or Viton® (FKM) in selected sizes and is extremely wear-resistant, with low compression set and high tensile strength. The material has a hardness of approximately 75 Shore A. The support ring is made of polyester elastomer with protective and extra lubricating additives, a material known for its high strength and heat resistance. The guide ring is made of thermoplastic material reinforced with fiberglass and additional additives. This material is characterized by high pressure resistance and good resistance to alternating thermal stresses.

Compact seals type DAS are self-acting double-acting seals. The radial force acting on the elastic rubber sealing element after installation is superimposed on the system pressure. This causes the total seal contact force to increase as system pressure increases. Good sealing is achieved even in the absence of system pressure. The wide mounting surface also provides additional protection against shifting or twisting of the sealing elements.

DAS compact seals are used as sealing elements for reciprocating pistons and hydraulic cylinders in earth-moving machinery, hydraulic excavators, cranes, forklifts, hydraulic tailgates, agricultural machinery, etc.
