- Piston seal- DK 143
Piston seal DK143 is a squeeze type, bi-directional piston seal for use in medium to heavy duty hydraulic applications. This seal is primarily designed for linear applications but has been successfully used as a low speed rotary seal. The standard material for this profile is polyurethane with rubber energizer. Polyurethan cap is energized using a resilient nitrile elastomer offering low compression set.
