The Incredible Resilience of Uponor PEX-a in Freezing Conditions

Uponor AquaPEX® is a flexible, durable PEX-a plumbing pipe that stands out in the building industry for its exceptional resilience in freezing conditions, making it a top choice for both cold-climate installations and areas that can be hit by unexpected midwinter freezes.

The manufacturing process for Uponor PEX-a pipe results in remarkable flexibility and elasticity, enabling the product to expand up to three times its diameter without rupturing, even when subjected to extreme temperature fluctuations.

This unique molecular structure, characterized by long, interconnected chains, allows Uponor PEX-a to have greater resiliency in freezing conditions far beyond what traditional plumbing materials can endure. So, whether it’s a sudden cold snap or prolonged exposure, PEX-a is engineered to maintain a plumbing system’s integrity, helping to ensure continuous water flow and safeguarding against costly damage.

With the freeze resiliency of Uponor PEX-a pipe, homeowners, businesses, and installers have greater confidence their plumbing systems will remain reliable and operational, even in the harshest winter environments.

Extreme resiliency

Unlike copper, CPVC, and other rigid piping systems, Uponor AquaPEX PEX-a pipe can expand and contract in freeze/thaw cycles to help protect systems from damage.

In fact, an industry technical report proves the durability of PEX through more than 400+ freeze/thaw cycles, maintaining flexibility all the way down to -40°F (-40°C).

Year-round reliability

Even in the coldest climates, or the most unexpected cold snap, PEX-a pipes can ensure uninterrupted water flow, helping to prevent costly repairs for homeowners and downtime for businesses.

Uponor AquaPEX pipe coupled with the reliable ProPEX® fitting system is confidently backed by a 25-year transferable warranty to provide even more peace of mind.

Application versatility

From residential plumbing to commercial installations, Uponor AquaPEX meets the rigorous demands of the project, no matter the size.

The product is engineered and manufactured to meet all local, state, and national codes and standards for strong performance and reliability.
