REHAU, an international manufacturer of polymer-based systems in construction, automotive and industry, has introduced the Firepex residential fire sprinkler system which uses the company’s EVERLOC+ fitting technology. The system connects using FIREPEX tees and elbows, RAUPEX white UV shield cross-linked polyethylene (PEXa) pipe and 3/4 inch through 2 inch EVERLOC+ fittings. 

The system works by carrying water through the shield pipes to fire sprinklers that are connected by the tees and elbows. When heat activates the fire sprinkler, a valve opens, allowing pressurized water from the pipe system to flow out. The flexibility of the PEXa pipe reduces the number of joints required compared to rigid piping systems and enables the use of compression-sleeve fittings that provide superior flow and security compared to insert fittings.

The product meets the requirements for residential fire sprinkler systems as defined by National Fire Protection Association (NFPA) Standard 13D Installation of Sprinkler Systems in One- and Two- Family Dwellings and Manufactured Homes and the International Residential Code Section (IRC) P2904.
