Wife bought good quality hosepipe & fittings etc recently. Yesterday she got hosed again after fitting slipped out. I tried everything I could think of before, but they failed all.
I went into garage and was looking for something else to try like an O-Ring, but then saw a selution staring me in the face….Its called a Copper Tube Sleeve(Just google the picture), use with copperpipe connections screwed on, not the soldering types.
Now the sleeve approximate the size will not fit, but you cut it through, then slip it over the hosepipe, ignore the 1-2mm gap now in sleeve. Now fit the pipe in connector at Tap or End of pipe, slip this sleeve over and in, now screw on the plastic nut which now will positively clamp the fitting.
The idea felt good trying to wiggle the pipe at fitting and even with high pressure did not kick out.
You may try it if you have such problems.
