Description
Decorating a room? Replacing a radiator? Normally that means draining the system, dealing with dirty water, and refilling and re-pressurising the boiler afterwards. With these patented Isolating Radiator Tails, you don’t. Fit them once between the radiator and the valve, and from that point on you can remove the radiator in minutes — no draining, no mess, no water waste, no boiler interference. A genuinely clever solution to one of the most frustrating jobs in domestic heating.
Sold as a pair (one for each end of the radiator). Fits standard 15mm x ½" BSP radiator valve connections.
Key Features

How It Works
The isolating radiator tail fits between your existing radiator valve and the radiator itself. Once installed, it incorporates an internal isolation mechanism that allows you to close off the flow at the tail before disconnecting the radiator — trapping the water in the system rather than releasing it. When you’re ready to refit the radiator, reconnect and reopen. The system stays pressurised and full throughout.

Frequently Asked Questions
Do I really not need to drain the system to remove a radiator?
Correct — that’s the whole point of the patented design. Once the isolating tails are fitted, you close them off before disconnecting the radiator. The water stays in the system. You can remove the radiator, decorate, and refit it without touching the boiler pressure or losing any system water.
Can I order if the item shows as out of stock?
Yes — we can fulfil this product even when stock shows as zero. Place your order as normal and we’ll confirm lead time with you.
Will these fit my existing radiator valves?
These tails use a standard 15mm x ½" BSP connection — the most common radiator valve connection size in UK domestic heating systems. They are compatible with all standard radiator valve installations, both new builds and existing systems.
Do I need a plumber to fit these?
The tails are designed to be straightforward to install. A competent DIYer can fit them, though we always recommend a qualified plumber for any work on a sealed heating system to ensure compliance with building regulations and to protect boiler warranties.
How many tails do I need per radiator?
Two — one for each end of the radiator (flow and return). This product is sold as a pair, so one pack covers one radiator.
Will fitting these affect my boiler warranty?
The isolating tails are designed to protect boiler warranties by avoiding the pressure fluctuations, air ingress, and inhibitor dilution that occur when a system is drained and refilled. Always check your specific boiler warranty terms if in doubt.
