Copper Crush Washer - Group Bleed Screw & Sight Glass

A small 12 x 6.2 x 1mm copper crush washer used in two spots on La Marzocco machines: under the group bleed screws and at the sight glass fitting.

SPECIFICATIONS

  • 12mm OD x 6.2mm ID x 1mm thick; copper

COMPATIBILITY

  • Fits: La Marzocco group bleed screws and sight glass fittings

INSTALLATION

DIY, quick swap whenever you remove either fitting.

PRO TIPS

  • Because it's copper, this washer work-hardens and takes a permanent compression set the first time it's torqued down, reusing an old one after removing a bleed screw or sight glass is a common source of small weeping leaks that look like a bigger problem than they are.
