Gas Compression Fitting

[halcyon]

Different world in the 1960's, health and safety ment something totally different. All buildings, and private garages were made from asbestos, insulated with it, and we machined it, we changed amonia barrels by hand without breathing equipment. My friend's dad was a gas board fitter, and tested the pipe when he moved the cooker with a bit of washing up liquid in water, and then got his box of XXXXXXX out to do a second test. The other funny thing was we lived then 200 yds from two gas holders, one suffered a fracture of the main feed pipe and started leaking gas. My friends dad was stationed at the pipe to watch it all night to monitor the crack, and he was a chain smoker, no one moved out, just went to bed.

The world changes and peoples views do, but history will always remain as it was.

I will promise to edit all funny historical stories for health and safety content in future.

This will do the job though you may not want to pay that much. You may be able to borrow/hire one.

Thanks - but it's a bit big as my pipe is only 8mm - looks like it will be mole grips until frustration sets in and then out with the hacksaw.

Alienzdive's method works, though I prefer to work round the olive, gently squeezing, so the olive expands without crushing the pipe.

philip just to attatch a bit of gravity to this thread. Im sure you are a very capable guy but your families lives depend on it with LPG.

Excuse me, I got slated for telling a true story, that at the time was in common useage. But am I realy reading here people re-using an olive !!!!!!!!!!!!!!!!!!!!!!!!!!!!!.
You cannot remove an olive, put it on a new pipe and reuse it, an olive is a one shot item. You may undo the nut and refit, but to remove an olive is taking penny pinching to the extreame, close on criminal.
Please throw them away a buy a new one to suit the fitting, if you cannot buy a new olive , buy a new fitting, after all gas has a habit of going off with a big bang.

I think the reason for removing the olive is not to save 2p for a new one,but to save shortening the pipe,I agree with you though . LPG in the wrong place can ruin your day.

But it's only 1/2" of pipe, and you still cannot put a new olive on an old bit of pipe, it's already deformed.

That's a big air gap between the fitted pipe and the fitted tap.

You buy a foot of pipe, a compression coupling, and a suitable olive for old tap or new tap, thus making up your 1/2".
I am happy doing a lashup to get a water pipe working, you can live with a slight leak, but not a gas pipe.

No, of course we're not suggesting re-using the olive! It's just that you can't put on a new fitting without taking the old olive off.

Personally I always either get a new fitting that will accept the old olives and compression nuts or scrap the whole pipe and start again.

p.s. the commonest fault with compression fittings is not cranking them up tight enough. If you remove the nut and you can still move the olive, it wasn't done up tight enough.
