The press by PEX design on NIBCO’s press transition ball valves needs no extra components to transition from copper piping to PEX, making connections from one piping system easier and faster while eliminating additional hardware and potential leak paths. Additional features include a compact design that installs easily in tight spaces, and a leak detection system on press ends identifies uncrimped connections during system testing. A stainless steel ring design on larger sizes also ensures a solid press crimped connection. Manufactured from a lead-free brass alloy, the valves are dezincification-resistant. Valves are rated up to 250 psi cold working pressure and feature a blowout-proof stem. Sizes range from 1/2 to 1 inch. 574-295-3000; www.nibco.com.
