Threaded screw-coupling reduction AGAflex 1 1/2 x 1 galvanised

AGAflex threaded screw-coupling reduction 1 1/2 x 1 in galvanised finish is a metal pipe fitting designed to connect or reduce threaded pipe sections from 1 1/2" to 1" nominal diameter. Manufactured in a galvanised finish, the coupling offers corrosion resistance and mechanical strength needed for plumbing, heating and industrial pipework where a secure threaded transition is required. The fitting is intended for use with compatible threaded pipe ends and appropriate thread sealants to ensure leak-tight joints for liquid or gas lines.

Advantages

The galvanised surface provides increased protection against corrosion and surface wear compared with untreated steel, extending service life in typical installation environments. The threaded screw-coupling reduction design allows straightforward installation without the need for specialized tools beyond standard wrenches. Its compact form enables reliable reduction between differing pipe diameters while maintaining mechanical integrity and ease of replacement when needed.

Suitable for (tasks / use cases)

• Reducing threaded connections from 1 1/2" to 1" in plumbing systems
• Connecting sections in heating installations and radiators
• Industrial fluid or gas lines where threaded transitions are required
• Temporary or permanent repairs where a durable metal threaded joint is needed

Key specifications

• Material: galvanised metal
• Connection type: threaded screw-coupling
• Nominal diameters: reduction from 1 1/2" to 1"
• Surface finish: galvanised coating for corrosion resistance
• Application: suitable for liquid and gas lines when used with appropriate sealing

How to use

Prepare both mating threaded pipe ends by cleaning threads and removing debris or old sealant. Apply an appropriate thread sealant or tape compatible with the medium (water, heating fluid, or gas) to the male thread according to manufacturer instructions. Hand-start the coupling onto the male thread, then tighten with a suitable wrench until a secure, leak-resistant joint is obtained. Avoid excessive torque that could damage threads or deform the fitting. Inspect the assembled connection for leaks after pressurising the system and retighten if necessary following safe working practices.

Usage recommendations

Use thread sealants or tapes that are certified for the conveyed medium and operating temperature. For gas applications, follow local regulations and perform leak tests after installation. Replace fittings showing significant corrosion, thread damage, or deformation to maintain system integrity.
