Radiator Reduction Valve Set kfa² 878-200-44 for 1 x 1/2" Connections with Accessories

kfaradiator reduction valve set 878-200-44 provides reduction radiator plugs and accessories designed to adapt radiator inlet and outlet fittings to a 1 x 1/2" thread. The set is intended for use when installing, repairing or replacing radiator connections in domestic and commercial heating circuits and helps ensure correct mechanical fit and leak-tight joints between different thread sizes.

Advantages

The set contains purpose-made reduction plugs and matching accessories to convert larger radiator connection points to standardized 1/2" fittings without the need to rework existing pipework. Manufactured to standard plumbing dimensions, the components simplify connection of thermostatic valves, lockshields or plain nipples and reduce the risk of leaks when installed correctly. Compact and ready to use, the set minimizes installation time for routine radiator service and replacement.

Suitable for

• Adapting radiator inlet or outlet fittings to a 1 x 1/2" thread
• Replacement of worn or damaged radiator plugs
• Heating system installation and radiator changeover
• Domestic and light commercial radiator maintenance

Key specifications

• Target connection size: conversion to 1 x 1/2" thread
• Contents: reduction plugs and accompanying accessories for radiator connection
• Application: radiator inlet/outlet adaptation and sealing
• Compatibility: designed for standard radiator fittings and common thermostatic or lockshield valve threads
• Material considerations: metal components suitable for heating systems (refer to packaging for exact materials)

How to use

Shut down the heating circuit and drain the radiator or local section before attempting replacement or adaptation. Remove the existing radiator plug or fitting and select the matching reduction plug from the set. Apply appropriate sealing material if required by local plumbing practice, then install the reduction plug and tighten to the recommended torque for radiator fittings. Reconnect the valve or pipework to the new 1/2" connection, refill and purge the radiator to remove air, and inspect for leaks at operating pressure.

Usage recommendations

Use in accordance with local plumbing regulations and industry best practice. Where material compatibility or system pressure ratings are uncertain, verify component materials and suitability before installation. If unsure about installation steps or torque requirements, consult a qualified heating engineer.
