Flair-It has introduced a new plastic plumbing system for use with PEX. The patented plastic clamp installs with a pair of pliers and can be removed with a screwdriver. The clamps are NSF- and CSA- approved for potable water and radiant heat, along with the Flair-It EcoPoly insert crimp fittings. PEXLock does not require expensive tools to install and no timely calibration. The sizes available are 3/8”, 1/2”, 3/4” and 1”. Flair-It has a large offering of all plastic fittings and valves to mate with the PEXLock.
