Universal Radiator Valve Extension | Fits 1/2″ TRV or 3/4″ Lockshield

Features

The Universal Radiator Valve Extension is a highly versatile problem-solver for central heating installations. It bridges pipework gaps when swapping radiators by adapting to almost any setup. Specifically, this rigid extension kit is built around a standard 15mm copper-sized pipe profile, allowing you to cut the length down precisely to your required size.

The kit includes a clever 3/4″ adapter fitting with a built-in compression nut and olive. If you are installing it onto a larger 3/4″ lockshield valve, the extension inserts directly into this adapter. For smaller 1/2″ TRV or lockshield valves, you simply reuse the compression nut and olive from the adapter to secure the 15mm pipe straight into the valve body. At the other end, a standard 1/2″ BSP male thread screws directly into your radiator inlet, delivering a professional, seamless look.

• Cut-to-length 15mm rigid pipe section allows you to customize the extension length perfectly to your specific gap
• Dual-compatibility kit fits both standard 1/2″ TRV/lockshield valves and larger 3/4″ lockshield valves using the included adapter
• Utilizes a secure internal compression nut and olive system to create an incredibly strong, watertight mechanical joint
• Universal 1/2″ BSP male thread end screws directly into standard domestic central heating radiator inlets

Details

When replacing a radiator, you rarely know exactly what size gap you need to bridge until the old unit is off the wall. Worse yet, older heating systems often use a mix of 3/4″ lockshields and 1/2″ TRV valves, meaning standard fixed extensions rarely fit everything. Buying the wrong parts leads to mid-job delays, wasted money, and the frustration of having to drain down the entire system to alter floor-level pipework just for the sake of a few millimetres.

This Universal Radiator Valve Extension solves these frustrations easily. Because it acts as a “one-size-fits-all” solution, it adapts to whatever valve setup you discover behind the old radiator. If it’s too long, you simply use a standard pipe cutter to trim the 15mm chrome tube down to the exact millimetre you need.

Additionally, the included compression adapter gives you total flexibility, whether you are hooking up to a compact 1/2″ modern valve or a heavy-duty 3/4″ traditional lockshield. This allows you to complete your radiator upgrade smoothly on the very first try. Consequently, you save hours of installation hassle and avoid costly emergency call-out fees from professional trades.
