Uponor’s ProPEX copper press adapters allow plumbers to connect PEX piping to existing copper press piping systems. They are made from high-quality, lead-free brass, meeting all local and national potable-plumbing codes, Uponor says. This is a flameless solution to make hybrid PEX-to-copper connections easy by utilizing existing tools that cut project timelines by up to 71%, the company notes. It incorporates a patented design for securely fastening the pipe and fitting together, eliminating the need for stainless steel rings. These are the only copper press adapters available in 2½” and 3” sizes, Uponor says.
