Centering Ring Assemblies, Stainless Steel

Centering Ring Assemblies include a supportive inner stainless steel ring and an elastomer outer ring (o-ring) which is compressed between the ISO flanges to create a vacuum tight seal.

Features

  • High Vacuum Rated to 1×10-8 Torr
  • Compatible with all ISO standard vacuum flanges
  • Reusable
  • Quick sealing and disassembly

Materials

  • Centering Ring: Stainless Steel
  • O-Ring: Buna-N, Fluorocarbon (FKM) or Silicone
  • Spacer Ring (LF sizes only): Aluminum

Product Notes

  • Metal centering ring aligns flanges during seal assembly and provides support for the elastomer sealing ring
