Cold expansion is designed for use with PEX-a pipe. To make an expansion connection, you will need an expansion tool, fitting, and PEX ring. The connection is made when PEX naturally shrinks back to its original size and forms a secure connection around the fitting. 

At the 2025 AHR Expo in Orlando, the Uponor brand was leading with water. The acquisition of Uponor by Georg Fischer (GF) has driven transformational changes that would not have been possible as a solitary organization.  With the help of GF, the Uponor brand has adopted new technologies that bring unmatched value to the market, many of which were showcased at AHR. Most notably, the introduction of Uponor ChlorFIT® Schedule 80 Corzan® CPVC along with ProPEX® to Schedule 80 CPVC transitions to provide a comprehensive commercial water solution spanning sizes ½" to 8". 

 A first in the industry, transitioning from Schedule 80 CPVC to ProPEX® has never been easier. Manufactured from trusted ProPEX Lead-Free (LF) Brass and Schedule 80 Corzan® CPVC materials, these new spigot and socket adapters in sizes from ½" to 3" eliminate unnecessary connections to provide 50% fewer installation steps for increased jobsite efficiencies while also improving system performance in commercial domestic water and hydronic heating and cooling applications.

One of the most important parts of any construction project, residential or commercial, is choosing a reliable, high-performance plumbing system. Equally important; choosing an appropriate fitting solution. The right fitting can ensure performance and reliability throughout the life of the plumbing system, offer unparalleled safety and efficiency, and promote profitability during the project and after it is completed. Choosing unreliable fitting solutions can result in costly failures that jeopardize your reputation as well as the safety and integrity of your project.  

PEX (an acronym for crosslinked polyethylene) is a popular, high-performance piping solution for residential and commercial applications. However, the assumption that all PEX is created equal is not true and can lead to costly mistakes. Using inferior PEX can result in troublesome issues, requiring expensive repiping efforts that can also damage your reputation with customers.

Uponor ProPEX® engineered polymer (EP) fittings undergo an extensive quality-assurance process that begins in the engineering design phase and continues through to production

Opus Mechanical used Uponor PEX-a pipe and ProPEX® fittings for the plumbing and hydronics systems in the new TPC Toronto Osprey Valley Clubhouse project. The efficiency of Uponor allowed them to comply with a tight construction budget and achieve an aggressive construction schedule.

A recent project in Northfield, Minn., was able to meet the needs of the engineer, contractor, and building owner by incorporating a complete polymer piping solution featuring PP-RCT and PEX-a for the domestic water system. 

What began in 1894 as a housing project for four elderly women in St. Paul, Minn., has grown into a comprehensive senior care facility serving residents with various needs. An expansion project, featuring Uponor PEX for the plumbing and mechanical piping systems, added new living spaces, a fitness room, salon, and theater to the complex.
