O-Rings for Breville Hose Connectors – 3.69 × 1.78 mm, 10 Pack

Hose Connector O-Rings for Breville Espresso Machines

Inside most Breville espresso machines the water and steam lines join with push-in connectors, and each joint is sealed by a tiny O-ring. Once these rings harden or flatten you can get slow drips under the machine or a hiss from the steam circuit.

Ten Rings, One Standard Size

This pack holds ten orange-red silicone O-rings measuring 3.69 mm inside diameter with a 1.78 mm cross-section, a common size in these hose fittings. Ten pieces is enough to redo every joint you open during a repair and keep a few spares.
