How compression fittings work - Plumbing Tips

In this video I show you how compression fittings work.

Compression fittings work by the compression of an ‘olive’ between two tapered surfaces and the pipe itself. The two surfaces are the body of the fitting (be it a valve, connector or any other type) and the nut. Using a spanner and a pair of grips the nut is tightened. This exerts pressure on the olive and bites it onto the pipe.

Masterclass in how to make a YouTube instruction video. Simple. Zero waffle. No music. Excellent visuals.

just sorted a plumbing problem in my old house and can now plumb in my sink. Compression rocks! Thanks!!

This is an absolutely exemplary instruction video - clear, simple, showing all the parts clearly, and very clearly narrated. And it really solved my problem. Well done Plumberparts!

legend has it he's still wrapping Teflon tape around the ferrule

A short but fantastic video which just helped me understand these little things. Replace one which had been leaking sneakily for months. Just saved hundreds of pounds on plumber and maybe on a damp course! Thanks Plumber Parts.

On boats we were taught to assemble the fitting, butt up the tube into the fitting and to mark the pipe with pencil. THEN WITHDRAW THE PIPE BY 1/4 INCH before tightening up. If the pipe is hard up against the end of the fitting there is no room for the pipe to move during tightening and the olive will be deformed. Think of the dynamics. The olive stays in one place. The nut needs to move along the pipe to make a seal. The fitting also needs to move along the pipe to make a seal. Try it!

Thank you. Just saved me from flooding the kitchen just that bit more. Watching your simple video has given me my power back. Yipee.

Thanks Plumberparts for sharing your video about plumbing! It's very helpful and informative.

Thanks for the help. Having never touch plumbing before (I'm a software engineer) I called 5 plumbers to be told I faced a 5 week wait to fit new bath and basin taps... YouTube pointed me to your videos so I purchased the flexie pipes, the weird spanner thing, a doubled ended "nut under the sink/bath tool" and some ptfe tape. I'm now tickled pink with my new taps and my house isn't flooded!! I have just noticed the smallest of weeps from a sink joint (one drop after 6 hours) but my water is rock hard so I'll leave it for a few days and hope the limescale sets and seals it!! Cheers mate, great video guides.

Great Video! Thanks for the very informative and useful video! Pipes, fixtures and valves for common plumbing can be connected in various ways. The easiest way to connect a pipe to another pipe, a fitting or a valve is with a compression fitting. This video teaches you how to use the compression fitting.

This video really helped me out today. Thanks for keeping it easy and simple.

Jon Flatman tip makes a lot of sense. I will be trying that tomorrow on a compression fit without teflon tape or compound. The purists do indeed say to avoid product enhancements (no such laws in the UK yet AFAIK) but I have noticed the drop in quality & consistency of materials. FWIW for the last 20 years I had been using tape particularly on radiator HW pipe couplings (which would most certainly weep after due to the expand/contract of the first heat cycle). I saw a pro use Teflon & he claimed he had a guaranteed success rate.

straight to the point instructional video, excellent!

Never heard of teflon being used on compression fittings, but it certainly does make sense especially after the ring/olive is compressed first.

Thank you for a simple and useful video.

brillant thanks mate i inboxed u on on facebook when my fitting at work was still leaking so ill put some off this tape on tomoz hopefully it will stop the leak

[rickyc]

Cheers buddy !!! Excellent video. Going to put it into practice tomorrow for the first time :)

[philbaggaley]

Thanks. Managed to fix my leaking washing machine inlet values.

[MohamedBhimji]

Great video - I understand how they work now, but have a question. I am installing a water filter (under the counter) and the tubing is plastic will the plastic compression sleeve work as well as a brass sleeve?

So I've got brass insert, plastic sleeve and brass compression nut.

Thanks in advance!

New tap fitted thanks to this. Thanks!
