WEDGIT

As the name suggests -these are useful in the permanent repairing or joining of 2 hosepipes or pieces of hosepipe of the same diameter. They boast the super secure bond of a double hose-nut, ensuring that the hose will not pull apart at that join again.

Available for 13mm (¹/₂″) and 19mm (³/₄″) hosepipe.
Hint: on old hose, dip the hose ends in a cup of hot water to soften them.
