O-ring 04131, Viton

A Viton (FKM) O-ring used in group head bells and boiler fittings across several commercial brands, valued for its resistance to heat and the mineral-heavy water inside an espresso machine.

SPECIFICATIONS

  • Thickness: 3.53 mm
  • Internal diameter: 32.93 mm
  • Material: Viton® (FKM)
  • Reference: 04131

COMPATIBILITY

  • Fits: Pasquini group head bells; also used on Bezzera, Brasilia, and La Pavoni (commercial) models

INSTALLATION

A straightforward DIY O-ring swap.

PRO TIPS

  • Viton is the right call here over a generic rubber O-ring, group head bell seals see sustained high heat, and standard EPDM or nitrile O-rings will harden and lose their seal much faster in that environment.
