Manufacturing the Highest Quality Products

There are many PEX systems on the market, but not many can guarantee you a controlled manufacturing process from raw material to assembly like SharkBite. As part of RWC’s brand portfolio, SharkBite’s owned manufacturing process means there’s better control over quality materials, inspections, product testing and assembly.  

RWC manufactures both SharkBite PEX-a and PEX-b pipe, which are certified to ASTM F876 and F877 and has the highest chlorine resistance and UV ratings. RWC also provides the broadest range of fittings systems through SharkBite — including expansion, crimp, clamp, push-to-connect and EvoPEX — so you can choose the system that works for you.
