Garden irrigation reducer coupling Cellfast 1" to 3/4" model 57-058

Cellfast garden irrigation reducer coupling 1" to 3/4" (model 57-058) is a compact mechanical adapter designed to connect irrigation components with differing connection diameters. It converts a 1-inch inlet to a 3/4-inch outlet, enabling compatibility between hoses, taps, sprinklers and other fittings commonly used in domestic and small-scale garden watering systems. The reducer is intended for straightforward integration into existing hose assemblies and irrigation lines where a size transition is required.

Advantages

The coupling provides a reliable, space-saving solution for adapting between 1" and 3/4" connections without the need to replace hoses or larger fittings. Its simple design allows quick installation and removal, minimizing downtime during assembly or maintenance of irrigation systems. The reducer ensures a stable mechanical connection that reduces leakage risks when properly fitted and complements a range of garden watering accessories.

Suitable for

• Connecting a 1" supply hose or tap to a 3/4" hose or fitting
• Adapting sprinklers, valves or timers with differing inlet sizes
• Temporary or permanent hose assemblies in domestic garden irrigation
• Small greenhouse or allotment watering systems

Key specifications

• Inlet diameter: 1 inch
• Outlet diameter: 3/4 inch
• Function: mechanical reducer coupling for irrigation connections
• Application: hose and fitting diameter adaptation in garden watering systems
• Form factor: compact inline adapter for tight installations

How to use

Turn off the water supply before installing the reducer to avoid pressure surges. Screw or push the 1" side of the coupling onto the larger connection and secure the 3/4" side to the smaller hose or fitting, ensuring threaded connections are aligned and hand-tightened; use appropriate hose clamps if required for barbed or smooth fittings. After assembly, open the water supply and inspect the joint for leaks; tighten connections slightly if necessary. For removal, shut off the water and reverse the installation steps.

Usage recommendations

Use the reducer coupling only within the typical pressure range of household garden systems and with compatible thread or hose types. Regularly inspect joints for wear and replace the adapter if signs of cracking or persistent leakage appear. Avoid using the coupling with incompatible chemicals or high-temperature fluids that exceed standard garden irrigation conditions.
