compression joint
A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connection. Compression fittings for attaching tubing (piping) commonly have ferrules (or olives in the UK) in them.
Compression fittings are used extensively in Hydraulic, Gas and for hot and cold water systems to enable the connection of tube (copper, steel Nylon etc) to threaded components eg valves and tools; compression fittings are suited to a variety of applications, commonly in water plumbing systems such as where confined spaces where copper pipe would be difficult to solder without creating a fire hazard, and extensively in hydraulic industrial applications a major benefit being that the fittings allow easy disconnection and reconnection.
Hello all, hope someone can help I'm after a joint which was missing from a purchase i bought years ago, just getting round to fitting it now, any idea where I can get one?
Pipe inlet is 18mm diameter and thread is 3/4" BSP
Yes, it me again.
I have a leaking compression joint that is connected to plastic pipe. I have now read elsewhere that it is not a good idea to connect plastic into compression joints. It DID have an insert in the plastic pipe.
I decided to use plastic JG speedfit pipe in the compression...
I understand that, at least in the USA, the term "Lead Free" means "not more than a weighted average of 0.25% lead when used with respect to the wetted surfaces of pipes, pipe lead-free compression fittings, plumbing fittings and fixtures."
In other words, Lead Free does not necessary mean Zero...
Hi, I have a standard radiator (1/2" female bsp) on which I'm installing a new lockshield/TRV kit. The lockshield is similar to this:
What happens if I remove the nut and everything on its left in the pic, and screw the valve directly into the radiator (with PTFE)?
This would simplify my space...
I need to replace an old leaking kitchen tap at a rental property and having fitted one of these before I've decided to go for the Cooke and Lewis mono mixer from Screwfix, which comes with 356mm flexible tales and a G 1/2" end:
The tenant has sent me some photos of the existing tap and...
I came across this for the first time yesterday, i have seen something similiar in the past when i was an apprentice but that was a long time ago.
Just thought that i would put this up so as to help anyone out there that may come across it. Its plastic pipe that takes cold main, in this...
I need to replace my kitchen tap and these are the existing pipes - any suggestions?
I was going to cut just above the connection with a pipe slice, install the new tap with flexi pipes and then connect it up with compression fittings/PTFE tape.
Does that sound sensible?!
Thanks.
Has anyone come across this? I've searched a lot and I can't find any instance of it. I'm redoing the plumbing in several rooms for different reasons and I've noticed that a previous plumber has used what appear to be solder ring fittings straight into 15mm compression fittings (no olive)...
Hi
I replaced our leaking bathroom tap yesterday, it’s one of these mono mixer types. The existing one had 2 copper connectors which then were connected to the plastic water pipes via plastic pushfit fittings. As the new tap had flexible connectors with a nut on the end I had to change the...
After four years of not leaking, the 10mm compression joint on one of my son's TRVs has decided to weep -resulting in combi pressure loss within a few days. I have slackened it off a tad and retightened and will keep an eye on it. It was already very tight, so I am expecting it to still weep and...
On 3/4 pipe, with a new 3/4 olive (brass, not copper alas) under a bath, on the further away of the two feeds, with bugger all space between wall, pipes and bath, using grips, tap spanner, adjustables, jaw dropper, no matter how many blood vessels I burst, are you guys all going to hand on heart...
I'm about to connect a replacement electric shower.
The shower has a 15mm plastic spigot and the cold feed has a 15mm brass compression joint.
I've read I should use a new copper olive, but should I also use a jointing compound or ptfe on the olive to ensure a good leak free connection.
Any...

Trying to add a bidet shower hose to my toilet. Am stuck at the joint as to what I would require to join the tee compression with the toilet tank. I have seen in you tube videos that the copper pipe slides in the tee compression hole but I got a piece of copper pipe and it just doesn't go in the...
Hey guys,
has anyone ever come across a rubber olive before? Every valve I've ever fitted up until now has a copper/brass olive compression joint onto 15mm pipe but this new radiator valve that I need to use for the type of radiator I have uses rubber olives to compress onto the 15mm pipe...
Does such a thing exist (40mm to 42mm chrome plated brass compression joint)? I'm have a nightmare trying to marry my shallow seal bath waste with existing 42mm pipe-work. Thanks in advance for any help.
I have a very old Ideal Standard boiler with a reserve tank in the roof. About six years ago a plumber fitted a compression joint underneath a newly laid wooden floor whilst it was being laid, and this has been satisfactory.
I am now thinking of replacing the boiler with a new system...
Hi all, could anyone help with some advice on this one?:)
I have been asked to do a few general maintenance jobs on a friends house (They now live abroad & are renting it out).
I'm NOT a plumber or Gas safe registered, happy with soldering copper pipe work etc, but want to stay safe &...
