    I have an old MDPE watter pipe that is approximately 22mm in OD, with a NB of approximately 17mm. I nned to repair a leak, any ideas where I could get a straight connector from to fit.

    I used a philmac UTC -21-27mm

    Where is the leak? outside

    I do not have a set of calipers, but 21.63 and 15.76 looks incredibly close.

    Leak is outside, the pipe was unfortunately less than 50 mm deep, and received a garden folk through it.

    The philmac UTC -21-27mm looks perfect.

    Jitender and KIAB, many thanks for the advice and help, massively appreciated.

    Will you need 2x pipe insert?

    I've had a look in the product manual, there is a product called ' Black2black' 7404 couple. May have to email them.

    But the philmac would work. 21-27mm - 21-27mm UTC

    I changed the stop tap here, and used the old copper insert, so will need them unless it is heavy gauge.

    Ben is just repairing the old black MDPE pipe, so 3G Metric/Imperial joiner is needed.

    I went from alkathene to 22mm copper, this is what Philmac advised for me.

    May be different for Ben.

    They were right with the UTC connector in your case Jit.

    Contacted Philmac, they said to use the 3G connection Joiner Pol x Pol - 9122

    A UTC 1144 would work, but is more expensive. No insert was is required for both fittings. It classed as 1/2" imperial.

    Perfect choice Jit, & only about £3 for a G connection Joiner Pol x Pol - 9122.
