43 x 48 x 3.6 Polyurethane Head Seal Metric

DR is a static seal used to seal the barrel to the head of the cylinder. The diffculties faced during an o-ring assembly such as twisting & ripping was solved with this design. It can be used without a back-up ring at high pressures. Due to the material, DR does have good wear resistance to extrusion and shows good sealing performance in static applications.
