Speedfit to copper

[PlumbersMate]

Is it true that you can join JG Speedfit straight onto copper with no inserts? Just slip the Speedfit straight onto the copper?

Yes.

As long as you cut it with a pipe slice, not like the joiner who plumbed in a kitchen sink with copper pipe and speedfit fittings and cut all the copper with a hacksaw. Ripped the o rings to shreds.

what are the inserts used for,not been funny,but i can't believe some of the questions,PLUMBERS ask.IS IT JUST ME OR DO OTHERS FEEL THE SAME, AM I BEING OBNOXIOUS OR HONEST.

I remember taking apart some stuff done by a kitchen fitter and each length of copper tube had an insert shoved up the end!

 

[PlumbersMate]

well sorry desrob but everything i was ever taught was with copper, apart from waste of course. No harm in asking, after all thats what i thought this forum was for? or am i missing something? I wasn't sure if i had to use a fitting, as I read you can just slip the speedfit over the copper, but to someone who hasn't used speedfit before this seemed a bit dodgy?!

Everything ive ever done is with copper as i believe a customer deserves the best for their money, and imo copper is best. Only reason i'm using it a lad I know wants me to literally throw a bit in for him so he can have an outside tap at his work, and the nearest point i can break in to is about 15 metres away from where he wants the Outside Tap

inserts are designed to give the plastic pipe a bit of rigidness, something for the grab ring to take hold of. Since copper is metal it is rigid enough and you don't need an insert and that's it really hope this helps

Thanks. Werent really the insert bit that was bothering me, just the fact that this gear just slips straight over the copper without leaking?!! lol Oh well you learn something new everyday

 

[GQuigley67]

get yourself some speedfit cap ends 15 and 22mm they are essential pieces of kit lol

 

[PlumbersMate]

have 4 of each, never leave the van without them! lol

as plumbersmate has never used inserts before it might be worth mentioning there are two one has an external o ring used mainly in heating it has a double seal in a sense and the second is just hard plastic more use for compression fittings if you use the ring seal in the wrong place it has very little bearing inside the fitting

Thanks billybob i did notice the inserts with o rings and wondered wether to buy them but luckily i got the plastic ones

 

[AWheating]

another thing to consider is never solder to close to a plastic fitting as the heat can damage the o ring's and shorten there lifespan.

 

[billybob150811]

no probs another little snag jg dont shout about dont clip too near fittings expansion ease off can be an issue hard to explain but you have to picture in your mind where ease off happens dont put fittings hard up against base units every situation is different but im sure you get my drift

 

[billybob150811]

rubbish post of mine if you clip the pipe it anchors it, The pipe then passes thru a base unit and a fitting is put on as soon as it passes thru the unit, as it expands and contracts the fitting can be slowly drawn off the pipe not often a real problem just worth bearing in mind

I understand what you mean.

 

[Dannypipe]

You mean if something presses against the 'release ring' that's around the pipe, then it can slacken the stainless steel pipe grip and the fitting can blow????

That's what I take it you mean.

Yes speedfit/Hep/ and all pushfit plumbing fittings can be used directly onto copper. Not chrome plated though as it slips. Good advise on not sweating a joint too near a pushfit fitting as you will damage the O ring.

 

[PlumbersMate]

Thanks for all the replies chaps. I'm glad I can debut this stuff in an empty dirty warehouse, so really doesn't matter if anything leaks, no cream carpets to damage! lol

 

[bashmaystor]

Yes you can use it with out inserts on copper pipe, and as said before as long as you use pipe slicer instead of an hacksaw. Speed-fit is better sometimes, when you have little access to run the pipes for example under the floor boards, or inside cavity wall. It saves you time and effort. But you have to be careful not to scratch or damage the outside of the plastic pipe, as it could leak if the rubber ring of the fitting sits on top of damaged (scratched) pipe.

 

[PlumbBobBob]

in the situation of having to pull through cavitys or under floors, i don't cut for fitting until afterwards so that i always have a clean undamaged end.

PlumbersMate you will get laughed at and teased here but stick with it and ask every silly question you can think of. Don't worry about it. I'm guessing you've done a fastrack course and are trying to get experience any which way toy can. Well that was me not long ago and I've spent the last couple of years here asking silly questions about obvious and simple things and now I only have to sound stupid about once every few days instead of every post. Regardless of how you're received just ask, ask and ask some more. I've learnt as much from the people on this site as I did at college.

Not quite a fast-track, but learnt at college through evening course around my old job as a duct fitter. And always go by the belief that theres no such thing as a stupid question, id rather ask and look stupid on here than not know and look stupid in front of a customer! lol

The advice on here has really helped me with things they just don't teach you in a classroom, and the advice has been great. All i can say is thanks to all of you

 

[leakeee]

inserts are for the expansion when the pipe heats up and cools!

expansion eh? so what happens when its used for cold then?. you dont need one!!!
there used to stop the pipe deforming in the fitting an to prevent crush in a simular way with comp fixings, copper dont deform.
