PTFE Gasket - 33 x 28 x 4 mm

PTFE gasket that seals the large nut on the top front of Astoria CTS group heads, a PTFE alternative to Astoria's rubber o-ring version (W80044) for higher heat and chemical resistance.

SPECIFICATIONS

  • Dimensions: 33 x 28 x 4 mm
  • Material: PTFE

COMPATIBILITY

  • Fits: Astoria CTS group heads
  • Equivalent to: Astoria rubber o-ring W80044
  • Works with: CTS group head top front nut

INSTALLATION

Simple DIY replacement, seats in place of the original o-ring/gasket during routine group head service.

PRO TIPS

  • PTFE holds up better than rubber under sustained heat, making it a good upgrade choice when servicing a group head that runs hot.
