The RadiantPEX-AL compression fitting system from Watts Radiant is as simple as it looks. All you need is a box-end wrench to tighten the nut. Made of solid brass, these fittings are made for long, trouble-free service. Double O-rings and a brass compression ring ensure a leak-proof connection. A polyethylene insulator protects against corrosion between brass and aluminum pipe layers.
