Capping speed fit pipes

[tomsim]

What is the best way to cap speed fit pipes? Speedfit push fit caps or compression?

 

[gas112]

inserts and compression

Thanks is this more permanent then the speedfit caps?

Are you capping the pipes permanently ? If so will that result in dead legs in the pipework ?

Im cutting them as close back as possible.

If possible you would take the tee out and replace with a straight.

...or put a Speedfit plug in place of the branch pipe.

...or at very worst have a tiny length of pipe then a Speedfit end cap.

Many people do it, but IMO putting a compression fitting onto Speedfit is a botch. They are not designed for each other.

Speedfit don't seem to have a problem with it.

Pipe Inserts

Offers extra support to pipework, ensuring pipe ends are kept nice and round.

If putting a compression cap onto Speedfit, make sure you use the plain inserts, not the ones with extra O rings.

Good call. I was unaware of that but, yes from my previous hyperlink, they do indeed recommend the ones without the O-rings.

Cant agree with that I'm afraid, that means that if plastic was used in a situation where everything else was copper/solder/compression then any compression fitting it would need to connect to should be changed?

Nah .... that's why the standard inserts are created with the strength that they have and why JG make standard inserts as well as superseal. The latter is used with their fittings to provide a triple seal, the former can be used with their own fittings and compression fittings. Very specific about that on their website. HEP2O also have a specific section about using compression fittings in their guide. What about compression radiator valves etc?
