Back-Up Rings

Back-Up Rings

For a variety of high-performance plastics we produce static seals for our customers. 
In conjunction with O-rings and other sealing elements support rings are used to prevent extrusion of the seal into the sealing gap.
Available from virgin and filled PTFE, and thermoplastic materials in different versions:

• solid
• cut
• concave
• individual Lasermarking
• and much more!
