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 5/8 inch BSP female inner thread (quite rare), the other a 1/2 inch BSP female inner thread.

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

Example of tap adaptor in use with outside tap

Unlike metric threads, 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.

3/4 x 5/8 x 1/2 Inch Outside Tap Thread Adaptor

Perfect fitting if you are changing your leaking, unreliable and grossly overpriced Hozelock garden hose fittings to cheaper but very reliable brass. Hozelocknozzle fitting on my hosereel is a 5/8" BSP thread (no-one uses this in 2017!) This converter piece has a female 5/8" end which is ideal to convert the hosereel outlet to 3/4" tap thread to receive your leakproof brass nozzle. Highly recommended and fast, excellent service from Stevenson Plumbing Supplies. (25 May 2017, 12:48)

This worked perfectly for my old outside tap. Much cheaper than replacing the whole thing! (13 May 2017, 16:32)

Just what I wanted to attach my garden hose to an old style outside tap with old thread type. (26 Apr 2017, 13:00)

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)

Just the Job!

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)
