Double ended brass adaptor fitting for older outside bib-taps.

Both ends have a male 3/4 inch BSP outer thread. One end has a 1/2 inch BSP female inner thread, the other a (rare) 5/8 inch BSP female inner thread.

Use this thread adaptor to allow connection of modern 3/4 inch Hozelock / Gardena type accessories to your older outside tap.

BSP (British Standard Pipe Thread) sizes don’t match up with what you would measure using a ruler. Have a look at the BSPT link at the bottom of this page for more information about how plumbing threads are measured.

I hadn't come across a 5/8" tap before I moved to my present house, and thought I would have to have a new garden tap fitted in order to use my hose pipe. Finding this adapter means that I don't have to do that now. Delivery was very quick. (23 Mar 2017, 15:20)

I have a 1960's outside tap and this adapter allows me to fit a modern day hozelock fitting to this tap. (10 Mar 2017, 08:23)

I have hunted one of these for ages.

I wish I knew about these before. Have looked in various garden centres etc. only to be told they don't make these anymore. Well they do and they work perfectly, so no more waiting in anticipation of my aged plastic one to break, happy days. Many thanks for the item and the speedy delivery. (30 Jan 2017, 08:56)

Everywhere I tried locally didn't have a clue what I was talking about when I explained what I wanted. Found this great value fitting on Stevenson site and received it in less than 24hrs. Fantastic service! (22 Oct 2016, 13:57)

This turned out to be the perfect adaptor for turning our old outdoor bib tap into 3/4" thread so we can use modern fittings on it. And delivery was really fast - next day. ( 2 Aug 2016, 10:02)
