O-rings for Breville BES920 double boiler espresso machines. Eight for hose connections, SP00001672. Six for boiler probes, identified as 5.6 and 6.26 in some Breville parts diagrams. Silicone. The photos are of the actual o-rings, the dime is shown for size reference.
If you are looking for fluorosilicone o-rings for the probes, the blue ones that were the original material used on the Breville machines, I have those available in another listing:
