Hmmm thanks, do you happen to know the chemical make up I'm looking for, or simply what the ones that came with the iHybrid are made of?
some o rings break down faster than others, this is where i shop, i'm no o ring specialist but i have bought o rings in the past that would look cool and after a week my tank started leaking, they were green.
Materials
Buna-N O Rings, Fluorosilicone Rubber, FDA or Medical use, is a plus
The standard rings are 5/8 OD with a 1/16, the extra ring Face sends is a super snug fit is 11/16 OD with a 1/16 wall
Example order, my last one
