Cold Expansion Polyalloy 90 Elbow - Products
A cold-expansion polyalloy 90 degree elbow turns a PEX-A expansion line a quarter-turn. With the cold-expansion (F1960) method, the pipe and ring are expanded and shrink back tight around the fitting, and the corrosion-proof polyalloy body offers full-flow, freeze-tolerant performance. Moonshine Bath stocks these elbows in common PEX sizes.
Polyalloy fittings will not corrode or restrict flow like some metal inserts. Each fitting ships free across the USA, Canada and Mexico, leaves the warehouse within 24 hours on weekday orders before 2 PM EST, and is backed by our price match plus 10 percent beat guarantee.
Frequently Asked Questions
What is a cold-expansion or PEX-A connection?
Cold expansion uses a tool to stretch the PEX-A pipe and an expansion ring. Both shrink back around the fitting to form a tight, reliable joint. It is the ASTM F1960 method associated with PEX-A tubing.
Why choose polyalloy over brass fittings?
Polyalloy fittings resist corrosion and mineral scaling, have a fuller bore for better flow, and tolerate freezing better than metal, useful in hard-water and cold-climate installs.
