DZR rod seals

DZR seals are hybrid rod seals and (fig. 2) combine an NBR primary sealing ring, a LUBRITHANE (TPU) secondary sealing ring and a triangular polyamide (PA) anti-extrusion ring into one seal. These combinations provide good low temperature resilience, and improved resistance to deformation, wear, and gap extrusion. They are suitable for extreme pressures up to 690 bar (10 000 psi) in heavy duty applications. DZR profiles are available in metric and inch sizes. For additional information, refer to DZR profile data.
