## Overview

The JD Brands 15mm & 22mm Grakob RCT3 Plastic Plumb Thumbs Radiator Capping Tool is a lightweight, durable plastic tool designed to cap radiator and towel rail connections securely without draining the system.

## Description

Radiator removal to many can prove to be a tricky task. It is well known that many of us have experienced dropping water or sludge from a radiator during the removal process onto floor coverings leaving the expense of a cleaning bill or worse still having to replace the flooring altogether. Plumb Thumbs saves both time and money on any job! It allows you to cap off the radiator as a fully sealed unit without the need for draining down and also makes it safer to carry the radiator from A to B.

Review: Great tool, must have for apprentices. - Great for removing rads without emptying and carrying outside without drips. I got a pair for myself a few years ago and have since bought 2 more packs for apprentices as a must have tool. Plastic threads so watch out for the odd 3/4” trying to cross thread, apart from that, don’t go mental on them and they will last. Highly recommend.

### ⭐⭐⭐⭐ Very good product, just an important drawback
*by J***E on 1 March 2026*

Very good and useful tool, used it on many occasions with no problems Only issue is that they are not metal and can cross thread easily and they don’t thread nicely onto older type 3/4” rad tails that are curved. Unfortunately I’ve had to bin mine as this style of rad tails cross threaded them. Still a very positive review overall as this lasted around 2 years+, Just need to be mindful of what type of rad tail you are threading on to.
