The seal ring on my 1725 Commer PB camper manifold shattered a while back. (It sits at the top of the downpipe).
I made one which lasted for a while but has now failed. Does anyone know where I can get something which will be compatible?
THANKS
 
The only one I can find is in Australia so no use but the listing does give measurements so you may be able to track down one with that information as they are not unique to a Commer.

Sealing ring

As a temporary fix you could try wrapping a load of copper wire inside the joint.
 
THANKS. I can't remember the last fix, possibly something similar, I will take the pipe off to see. I once tried the rim of a fire blanket wrapped round, which lasted about 100 miles in short trips. I was looking today at the idea of welding or brazing a steel break pipe into a circle to make a seal (with an exact fit steel brazing rod in the middle of the tube to improve the join). I however am aware that the steel used on break lines is a kind of rust resistant alloy, so it may be interesting to see what happens if I try to weld it with a TIG or MIG. It might try TIG and feed severed break pipe in to the join. (Digi TIG is my new toy, so I have some learning to do). So many jobs to do and too many cars, but I can't say I don't enjoy tinkering about and getting my hands mucky. Today it was a day off and between several cups of tea I fixed a clutch fluid tube and fuel leak on the Commer, so I made some progress.
 
Buy a 6x50mm stainless rigging ring on eBay then cut and shut it to fit with the TIG welder. Yes I know it's round section, but it should seal OK when tightened up.
Just a suggestion
