GGDA-SP PISTON SEAL
Single acting captive slide ring o-ring seal GGDA-SP can be used in combination with other single- or double acting sealings on the piston.
These arrangements can improve and increase tightness and sealing effecieny of multiple demanding hydraulic applications. GGDA-SP consists of 4 parts, one step-profile PTFE slide ring, 2 L-shaped support rings and one elastic energizer O-ring.
