8mm Propane Gas Valve

[Merryterry]

I am looking for an 8mm spigotted Gas Isolating Valve (or a F/I screwed Val= ve and some M/I spigots)to cut into the 8mm tube to my propane greenhouse h= eater. All the ones I can find are Compression Fittings. I know I could put= a piece of 8mm copper tube either side and use hose clips but I dont think= that that is permissable.

The problem is that I turn the Gas off at the Gas Bottle most nights and it= takes an age to purge the air out of the 1.5 metres of rubber tubing and g= et the pilot to stay on. If I put a valve adjacent to the heater this shoul= d cut this problem down.

Why not? - what's the rubber hose held onto the heater and regulator with now?

Why not just turn the heater off and leave the gas bottle switched on?

Use flair fittings.

Would something lie a non-return valve at the heater end of the tube work?

Search ebay for "8mm non return valve"

Or depending on the fitting to bottle/heater a hose with an inbuilt non-return valve. BES is one company that has these
