For more than 20 years, Uponor AquaPEX® has been the gold standard for flexible, durable, easy-to-install PEX plumbing systems. Uponor AquaPEX is Engel-method, PEX-a crosslinked polyethylene tubing that offers the highest degree of crosslinking (around 85%) for unmatched flexibility, durability, kink resistance and freeze resistance in the residential and commercial plumbing world. And because it’s not a metal, AquaPEX is immune to the corrosion, pitting, scaling and lead-level concerns that can plague alternative plumbing systems.

Because of its flexibility, Uponor PEX-a tubing is faster and easier to install, requires fewer fittings (up to 40% fewer to be exact), and saves incredible labor time (which can equal greater savings for you). And AquaPEX uses Uponor’s ProPEX® cold-expansion fittings for strong, durable connections that hold tight with up to 1,000 pounds of force — without the need for torches, glues, solvents or gauges — and with no dry-fitting concerns.
