NBC autoweld liner

[Ric]

Other than a museum does anyone know where I can get a steel liner for one of these. Looks like an odinary piece of liner with a crimped olive close to the end.

hi there pic of the offending item might help the identification process

Hope this helps, there are two bits crimped to the liner, the screwed part belongs to the gun.

Isn't that just a standard euro torch liner but an older type?
That piece with the thread on each end should stay in the connector and the liner is passed through it, pushed up to the torch then secured with the nut.
New liners have a brass piece crimped on to the end instead of olives as yours has.
Weldequip sells them in the forum shop

Here's one Shenion showed us a pic of a while back.

Does the large brass piece on the liner in your picture come off leaving a small crimped bit? Does anyone have a close up of the end of a eurotorch liner to see if I could adapt it?

As I said, that brass ferrule on the liner should just slide into that double ended threaded brass piece that's loose on your liner, the nut then screws up to the shoulder securing it.
That double ended piece is part of the plug and doesn't need to be removed, just the nut is removed then the liner pulled out.
You'd have to measure the internal diameter of that piece and get the OD of the ferrule on a liner to make sure it fits.
If not then you might simply have to buy a longer liner than you need, cut the ferrule off and wrap a few turns of mig wire around it instead of using an olive as it is now, it's only to hold it in place.
TBH, that's probably your easiest option.
All the steel liners I've seen have had that ferrule crimped on, the only ones I've seen it loose on are teflon ones.
Like this.

Thanks for the help. Looks like the easiest option is to buy a euroliner and cut the end off, doubt if there will be enough room for the plastic outer but that should come off easily enough.
