Use these Heavy Duty fittings to either repair a damaged hose or to join 2 lengths of hose together

They can only be used for joining hoses of the same diameter. 

They are made from 3 polypropylene components with nitrile rubber seals between the joints.

They are available in 6 sizes for 1/2" standard garden hose up to 2". All hose tail dimensions are the external diameter of the hose tail and the internal diameter of the hose to fit.

Fitting                

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
