Barbed Hose Reducing Coupling for Irrigation Lines

This barbed hose reducing coupling joins two irrigation hose runs with different listed connection sizes. Its straight body places the larger hose tail and smaller hose tail in line, creating a simple transition at a change in hose diameter. Raised rings on both ends provide the visible hose engagement areas, while the stepped middle section makes the two ends easy to distinguish during preparation.

Select the two hose sizes

Choose from 75 x 63 mm, 90 x 75 mm, 90 x 63 mm and 110 x 63 mm options. Both numbers matter: the larger end must suit one hose and the smaller end must suit the other. Confirm the required hose bore and its suitability for a barbed insert connection rather than relying on the hose's outside measurement or a visual comparison with another fitting.

Plan a tidy line transition

A reducing coupling is useful when adapting an existing irrigation run to a differently sized section without adding a branch. Position the joint where you can support both hoses and reach the connection for inspection. A change in line size can affect system flow, so consider the layout and water demand of the connected run when planning the transition.

Prepare and inspect the joint

Cut hose ends square, remove loose debris and check for splits or distortion before fitting. Push each compatible hose evenly onto its matching tail, following the hose manufacturer's assembly guidance. Use suitable clamps where the hose type and operating conditions require them. Arrange the hose so bends or unsupported weight do not continually strain the connection.

Restore the water supply gradually and examine both ends for leaks or movement. Recheck the joint after the first irrigation cycle and during regular maintenance. Each selected option is one coupling; hose and any additional securing hardware should be planned separately.
