Durapipe water pipe leak fix?

[muttyhc]

Dear All,

I have durapipe (light grey pipe 1970s use) in my house. It is all over the house so for certain repairs I have bought some universal couplers which have worked well.

However, I have noticed that on a join under the kitchen sink, the pipe is dripping. It seems to be a crack in he joint.

I tried using LS-X sealer but it made no difference. Is there a way to temporarily fix this until I am able to replace the pipe?

I would use a coupler but the space is very limited.

I have looked around on the net and there really isn't much information out there.

I found - 3 8in Durapipe Polyorc Iso 17mm OD x 15mm Copper Compression Transition Adaptor

but do not know if this will work.

Any advice or help would be appreciated.
