It's been used to link between the dec gas fire and the feed on to the gas.

The feed is 15mm to 8mm copper reducer and then this tube is simply pushed over the 8mm copper reducer by 30mm or so.

Is gas fitting really that simple and does the pipe not require a jubilee clip over it or some sort of bonding ?

So how does it work ? Do the inner fins provide some type of seal ?


Another question, is it available in all gas feed sizes such as 15mm and 22mm ?


Questions, questions, questions............ Thanks for any help.

polish plumber?? that nasty!!

if that's the gas connection
$1 says it deffo hasn't had a spillage test either

That's the SLEEVING which has been taken OFF a pre-sleeved gas pipe which is designed for use with some fires. The ribs are designed to let gas out IF the pipe has a leak so you can smell it. It's NOT a gas pipe by itself!!

Its Wild West Gas Services again.....I'm not sure even a cowboy would do that though. Looks more DIY to me, but I stand to be corrected.

What colour is the plastic? I am tending to agree with Chris.

Plastic covered copper pipe is the one that must be used for fire connection.

dont be silly noone in their right mind would fit a fire and not spillage test it.

Chris is (obviously) correct, it is a sleeve off a presleeved tube. this tube can be used through walls without further sleeving, as opposed to normal factory covered tube.

Having said that, I beleive the post MUST be a wind up. Theres no way that the sleeve can be pushed onto 8mm tube and not p*** out gas. The channels are there to ALLOW the passage of gas!

Not a wind up at all.

I might have viewed in incorrectly under the floor.

Last year I had a new fire fitted and the tube sleeve I pictured was found while I was doing some underfloor rewiring on Weds.

There's a 15mm gas copper service feed sub floor, this then has a reducer and then the pipe / sleeve runs up to the fire.

Here's a picture of the fire end of the pipe.

I got a British guy to do the work and I got posted a Gas Safe ticket, so the work was / should have been done correctly.

Looking at the other end it appears (to my eyes) to be a microbore pipe with a sleeve, and the sleeve I found was (maybe) the stuff taken off to allow the connection on to the 15mm main gas feed.

Does anyone agree, or is it something that is wrong and needs remedials ?[/img]

 

[kevplumb]

no it's the sleeve the copper runs inside it

should have posted these pics in the first place

a picture tells a thousand words
a thousand words can tell bol***ks

The pipe is fine. But, thinking about it, if you were so concerned, why consult a forum?

If in any doubt about agas leak phone Transco, or whatever they are called at he time. They may be carp,but they'll make safe.

Having re read Chris' post, there may be one deficiency. typically, only appox 1 metre of 8mm tube is allowed. I always run 15mm into the FPO, then reducw to 8mm. Apart rom pressure loss, it is easy to kink 8mm tube, (say, on servicing) so my reducer is ALWAYS in accessible position

I've just had a new gasfire installed and I noticed a kink in the pipe, is it safe or should a new length of pipe have been put on?
