Plastic hose joiners are available in the following sizes :
12mm,19mm, 25mm.
These are preferred to steel type joiners which often have sharp edges. Such edges can cut the inner wall of a reinforced P.V.C. hose and cause water or air to pass between the two walls of the hose until a weakness is found in the outer wall. At this point, the outer wall expands under pressure and inevitably bursts.
