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

Specifications

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

*Dimensions are in inches unless otherwise specified
