Uponor recommends expansion joints for every 50 feet of tubing to accommodate the expansion and contraction of PEX-a tubing caused by temperature changes. To reduce labor and costs required to build a joint from scratch, Uponor created this industry-first product for commercial plumbing applications. The unassembled kit includes one pre-formed 2" expansion loop, two 2" brass elbows and four 2" ProPEX® Rings.

The kit is 44% less expensive than purchasing the 13 individual components (four feet of tubing, four elbows and eight rings) needed for onsite construction of an expansion joint. And, not only does the kit cost less than buying the individual components and saves time over building a joint from scratch, because the kit requires fewer joints, it also provides more reliable performance.
