Barbed Hose Pipe REDUCER/Joiner. 15 Sizes. Menders, Repairers, Couplers
Use these fittings to join 2 lengths of hose together which are of different diameters, extending the total length of your hose. They will also help improve water pressure at the delivery end. They are light weight but extremely strong one piece items.
They are available in 15 Sizes:
Fitting couldn't be simpler. Push the hose pipe ends over the barbed tails as far as they will go. This will normally suffice for normal or gravity fed water pressure.
If the water pressure is high or you have problems with the hose coming away from the tails, then you may need to use "jubilee" clips or hose clips to secure the hose pipe to the fitting.
If you have difficulty getting the hose to go over the bargs, soak the hose ends in very hot water for a few minutes. This will soften the material and make it much easier to push the hose on. When the hose cools it will shrink and form a strong watertight seal.
