Hi all. I have an external BBQ that has a hose connection. Within that screw connection is a very small rubber doughnut ring sealing washer. It is found in plan view but also round in cross section and not flat like s tap washer. This has perished and split. Please see photos. Just wondered 1) what it's called so I can look for one. 2) where should I go looking?
Many thanks....
