Hosepipe fittings issue

mark.wingfield

My mum has purchased a new hosepipe to replace a split hosepipe. She has an outside tap that has a brass male connector which appears to be soldered or fixed to the end of the tap. Her old hose used a brass female connector that was a 3/4 inch male thread at the other end and that screwed into the fitting directly on the old hosepipe . The female connector is a tight secure fit to the tap male connector and this comfortably handled our water pressure.

Her new hose comes with a plastic female connector so I tried this directly on the male tap fitting. This could not handle the pressure and blew off every time. Just trying this on a spare plastic male connector is pretty strong but the brass tap male connector must be a slightly different shape as it is not a strong connection.

I have been looking at still using the  brass female connector with the 3/4 inch thread the other end, as this is so sturdy. However, finding such a fitting for the setup of the new hosepipe has been so far unsuccessful. Looks like I need a 3/4 inch to 1inch screw adaptor of some sort to reuse this strong connection (please see pictures).

Can anyone help as the hose is useless if we cannot connect securely and any new hose would probably have similar issues.

The tap connector looks as if it ought to be removable. It's like mine, the tap itself has a screw thread on the outside and the brass connector screws on to it. Sometimes it gets very tight when it's not been taken off for a while (I blame the limescale) and then it needs some wd40, leaving for a while and then a pair of maul grips or similar to undo it. Maybe you could try that if your quest for a female connector isn't successful.

Another thought - the brass connector on the green hose looks as if it ought to separate into two parts - between the two knurled grip parts. Does that leave you with the right size thread to attach the brass female connector from the old hose?

Very unlikely that the adaptor has been soldered to the tap.  As JennyJ says, some penetrating oil and decent grips will almost certainly remove it.

I agree with the previous replies, but you should be able to get metal fittings if you want. The people who do Access greenhouses etc sell them, so do two West's and Elliott , I'm sure there will be others on tinternet.

Yes, remove the existing brass part from the tap (a 'footprint' pipe wrench always helps with those) and the black plastic part in the new kit should fit directly by the looks of it (3/4" BSP thread.) The green adapter in the new kit is in case the tap has a 1/2" BSP thread.

Struggling with taking off the brass connector from the tap. Used oil and wrench. No movement at all. I accept that it seems more likely that it is simply screwed on but it really does look like it is inextricably connected.

You could try putting a little WD40 or 3-in-1 on each day over several days and let it slowly seep in.
Also try pouring a kettle of boiling water over it slowly, as the metal expands then contracts again it can dislodge the limescale
I'm sure you'll get there

As everyone has said, it should unscrew.

I'd use two Mole grips, one on the body of the tap and the other on the bit you want to unscrew,

With one hand on the the grip on the body, while you turn the other on the bit you want to unscrew, as there's a danger of you ripping the fitting off the wall if you turn too hard..

You could try a bit of heat on the bit you want to unscrew.

Agree, if penetrating oil doesn't do the trick, heating the brass part with a blowtorch should help (best to turn off the water supply to the tap first, then open the tap, or you'll have yourself a mini exploding boiler.)  I have very hard water and limescale build-up on taps and pipes always makes what should be a simple 2m plumbing job take all day.  Or longer!

The male brass connector that is permanently stuck onto the tap was probably designed to mate into a female connector which uses three ball bearings as the retension system instead of the three white clips as seen in the plastic connector (pic 2).

This means that the male connector has a banding ridge designed specifically for ball bearings and, consequently, the plastic clips can not lock securely into place.


If you can screw the green plastic reducer (pic 5) into the end of the old hose connector then this will tell you that the thread on the black plastic male connector (pic 5) and the thread on the brass female connector (pic 7) are the same.

In which case, just grind/cut off the unthreaded section (with the red seal) of the female brass connector so that you can screw the black plastic male connector (pic 5) onto it.

Thus, you will have brass female, plastic male, plastic female attached on the hose side.

The horrible truth. So many different types are nearly compatible but leak, even using all hose lock stuff can leak. Your collapsible hose is very delicate, don’t stand on it. Inside is a thin pipe, these have a tendency to pop
