RTM (Ring Tension Memory) Technology - Uponor’s Answer to Push-Fit Connectors

RTM Technology – a leak-free mechanical connection that’s the best alternative to plastic push-fit fittings

Close-up Illustration of Uponor’s RTM Technology Fitting
As an alternative to a Push-Fit fitting, why not try Uponor’s unique RTM (Ring Tension Memory) technology with the ‘tool-inside’ concept for a tool-free press connection.

Enjoy the feeling of security from a fast, simple, professional press connection without the need for expensive tooling.

The RTM fittings’ audible ‘click’ upon making the connection gives complete peace of mind the joint is secure. Additional comfort can be gained by using the 360° visual inspection window to view the pipe and its correct bon­ding into the fitting.
