Tool inside concept for fast and safe radiator connection

Choose our revolutionary new RTM Technology and you can be confident of a highly professional job every time. This is the plumbing joint of the future, helping you create perfect pipe connections, quickly and securely without hassle and without tools. You’ll know instantly when a connection has been properly made, resulting in a long-lasting, leak-free joint.

RTM Technology is designed to work perfectly with Uponor’s MLCP pipes. With our five layer composite pipe, we have developed an advanced product that unites the advantages of a metal and plastic pipe and eliminates the disadvantages of both materials at the same time. This offers product advantages that are second to none.

RTM joints are available in 16mm to 25mm diameters and are colour coded to show at-a-glance which size to select. This saves you time and avoids any chance of error. The end result is a safe, professional job you’ll be proud of.

Every RTM connection is quick and easy to make. Simply insert our MLC pipe into the fitting until you hear the distinctive click. This indicates that a secure joint has been made. You also have visual proof of success thanks to the 360º window, so once fitted – it is done!
