STYLE DZ U-SEALS |
![]() |
|
The Z-Seal is a squeeze type seal, combining the
excellent sealability and low compression set of a
resilient rubber lip with the greater anti-extrusion
characteristics of a hard thermoplastic base. Under
low pressure conditions, the sealing lip provides
its own compressive seal force. As pressure
increases, hydrostatic pressure is mechanically
transmitted through the elastomeric seal element
into the anti-extrusion base. The applied force then
deflects radially in a controlled manner, closing
the extrusion gap behind the sealing lip. Under this
condition, maximum sealing effectiveness is
achieved.
