Description
Series T 20 U-rings for sealing rods and rams are made of NOVATHAN material. This material is a polyurethane which is particularly resistant to abrasion and extrusion.
Further outstanding features are :
of this material as well as the low compression set of only 26% after 24 h at 70° C.
The U-rings are asymmetric in section with a shortened inner lip. To achieve an initial sealing force, the U-rings are produced with lips that are wider than the nomnal section. During operation the system pressure is superimposed on this initial pre-load, thereby increasing it. The lips are designed for optimum sealing in all pressure ranges as well as in a "zero pressure" condition.
Further outstanding features are :
- good thermal stability
- good resistance to different media and
- good elasticity
