HeatLink’s F1960 PEX-a potable water expansion system features PureLink Plus PEX-a tubing, high-performance polymer fittings and multiport tees, no-lead (Eco) brass fittings, and PEX-a expansion rings. The PEX-a expansion rings use the strong shape memory of PEX-a to form a watertight seal. The PEX-a tubing and expansion ring are expanded with a specialized tool and are allowed to contract in order to form the connection, HeatLink notes. HPP and no-lead brass fittings are available in 1/2”, 3/4” and 1” sizes for all small-dimension plumbing needs.
