NBR O-ring Gasket 0170-30 Ø 23×17×3mm for Brewing Group Plug

This NBR (nitrile rubber) O-ring gasket seals the brewing group plug on ASTORIA/CMA espresso machines. When the gasket perishes or compresses over time, you'll notice weeping around the group plug or loss of brewing pressure—replacing this seal restores a reliable watertight connection during extraction.

Made in the EU from NBR with precise 3mm ring thickness, this gasket ensures consistent compression and sealing performance on the Ø 17mm internal bore of your brewing group plug assembly.
