AquaPEX tubing from Uponor is the only PEX-A grade potable water PEX sold on PexSupply.com. PEX-A is the highest grade for PEX. Its superior shape memory makes it more flexible and easier to work with. It has better freeze-resistance than PEX-B and PEX-C tubing, and gives installers the ability to fix kinks by applying heat. Only PEX-A is compatible with expansion-type fittings. Such fittings, including Uponor’s ProPEX fittings, have a larger diameter and provide more flow than any other type of PEX adapters.
AquaPEX tubing comes in red, blue, and white to make it easy to identify hot and cold lines. Pre-insulated AquaPEX comes pre-fabricated with 1/2” of insulation with an R-value of approximately 3.0 (depending on tube size). The insulation adds to the tubing’s freeze-resistance, slows heat loss, and helps save time during installation.
