JOHN GUEST PIPE CONNECTOR. Push-fit Tube O.D. 1/4" to 1/2" BSP Thread. Speedfit Part No CI320814S. Inch Size Threaded Acetal Fittings for Drinks Dispensers and Pure Water.

This is brilliant. When my fridge arrived with a 24mm connection but the builders had left me with. 15 mm connection I tried to use an adapter but despite a plumber trying and copious amounts of ptfe tape it still had a very slow leak. This was screwed hand tight and pushfit to the tubing and no leaks at all. Why I can’t find this in the major diy stores I have no idea, but it is excellent.

Good genuine part that fits well to 1/4 water pipe with no leaks.

Good quality as and easy to use.

Used for connecting my ball fix valve to a fridge. Make sure you understand what BSP sizes are before you order the size you need. The connector seems well made and works as intended. If you like the added security of a circlip you will need to purchase one separately as this connector doesn’t come with one.

I had just changed the filter on my drinking water tap, when the push in plastic junction on the feed started to drip. I thought I would need a whole new unit, but saw this on Amazon, and bingo, it worked a treat.

Got to fit new fridge freezer fitted well and no leaks

Did not seal when fitted at first, but then I noticed the inside of the fitting has a raised wall (see other reviewers photo) and not a flat area as the item description and item photo. It was then a case of PTFE on the thread and almost over-tightening to get the rubber to make contact with the isolator valve and form a seal.

Just what I needed, did the job its intend for.
