Under body heater tube

[Manxfella]

I need to replace the steel underbody heater tube.
How have people fitted this? Straight forward tack welding or have you sleeved the 2 ends & slid the pipe over for a tight fit?
Thanks.

My bus had a plastic pipe instead of steel
Looked like something u can buy at a hardware store
Don't know if it was working as I bought it as a shell.
Will never rust !!

You mean something like a piece of drain pipe?
It gets pretty hot at the business end. Worth looking into though.

On my old bay I had a plastic jobbie that was made for the job, sands of time have covered it's tracks but it was from one of the big players like JK etc

Don't know if you've found this before, but thought I'd put the link up anyway.

By the way, some time ago I found a company that did a plastic version of the rear Y section, but I've lost the link. Anybody know who did them?

That link from heritage is a steel pipe & is the one I've got. Pretty substantial piece of metal.

Sleeving & bonding looks like the way forward.
