Build on S-Press PLUS - the new fitting range for metal pipes

Installers around the world and the UK build on Uponor. After 25 years of real life experience and more than 500 million fittings installed, Uponor has now reinvented the press fitting system for metal composite pipes.

Introducing S-Press PLUS: the perfect solution for ensuring permanently tight pipe connections. Available in dimensions from 16 to 32 mm in both metal and plastic (February 2020), it is 100% backward compatible with current Uponor multilayer pipes (MLCP) and tools. What's more it offers improved flow rates and resilience against harsh conditions onsite.

It truly is the plumbing fitting which knows no compromise, perfect for metal composite pipes as well as plastic ones.
