O-rings for Breville BES900 BES920  BES980 BES990 double boiler espresso machines.  Eight for hose connections, size SP00001672.  Six for boiler probes, identified as  5.6 and 6.26 in some Breville parts diagrams.  These are fluorosilicone, that's why they are blue.  Customers have been asking for these because they were used in the original machines for the boiler probes, but hard to find.   Now we have them.  Superior to silicone in temperature range and durability. 

If you order by noon EST I have them shipped from NJ the same day.  I ship Saturdays too.  Delivery is typically 2 to 4 days in US, 7 to 14 days international. Get that machine fixed fast.   I specialize in o-rings and Ulka pump repair kits, check my feedback, all my happy customers.

If you need other o-rings, please contact me.
