This brass thread adaptor connects modern 3/4 inch BSP (Hozelock / Gardena type) garden hose pipe quick connect fittings to the outlet of your older outside bib tap.

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

Great for old outdoor taps with the less common 1/2 or 5/8 inch BSP size outlet threads.

** Unlike metric sizes, imperial BSP thread sizes are measured a special way - have a look at our information page for more details **

Outside tap adaptor-BSP threaded

Thank you to Stevenson’s for the very prompt delivery of this perfect fitting. After trying unsuccessfully to replace an existing worn out BSP thread plastic connector we spotted this brass fitting in Stevenson’s website. Delivered in a couple of days, fitted on to my old tap immediately and I now have the hose back in action! Thank you ( 4 Aug 2021, 08:21)

5/8" x 1/2" x 3/4" Outside Tap Connector / Garden Hose Fitting Adaptor

Went to a local plumbing shop seeking a connector for my old tap. Didn't fit so I used Stevenson Plumbing's web site I found the connector after a few clicks. Delivered within a few days - best buy at a time when the weather is getting really dry again. Great service. (17 Jul 2021, 14:21)

Wrong fitting

Received this promptly but unfortunately does not fit my 1970s outdoor tap. ( 4 Jun 2021, 11:29)


My Husband considers himself VERY fortunate indeed to have discovered STEVENSON PLUMBING ORGANISATION. They have proved to be most knowledgeable and helpful and extremely efficient solving an aged (Imperial) garden hose connector problem. The speed of delivery was fantastic. D.A.C.
