Group Gasket NG01/001 - Mine is 8.5mm thick 57mm ID 72mm OD

Tex at the Gaggia Users Group recommended I use a $6.06 E-61 Soft 8.5mm Group Head Gasket from Espresso Parts


Last item on the list is 4 DM0701 Belt - Spring clips to secure latex tubing.

Still Researching but these may work:

Acetal Snapper Type Hose Clamp, Quick Ratchet Closure, For 3/8" Nominal Tube OD, .351-.394 Clamp ID (Pack of 10) $4.55 at Small Parts

These are plastic so they will not rust like the original ones did.


This is  a helpful o-ring sizing chart

A potentially sleep inducing 256 page technical handbook on o-rings - could be handy
