A Superior Expansion PEX System

View All PEX Products

It Starts With Superior Pipe

Zurn utilizes a proprietary variation of the silane method along with our engineered pipe formulation that produces the highest temperature/pressure resistance, highest chlorine rating, extended UV resistance, color throughout (not just on the outside), and maintains flexibility. The same pipe can be used with expansion as well as crimp fittings. Our products are engineered to perform in the toughest plumbing conditions and stand the test of time.

Expansion or Crimp — Same Pipe

The same pipe works with expansion PEX (ASTM F1960) and crimp PEX (ASTM F1807) systems and is available in 3/8” – 2” sizes. Our products are third-party certified for both standards and can be used with brass or polymer fittings.

Backed by an Industry-Leading 25-Year Warranty

We're so confident about the quality of our product that we gave it a 25-year warranty. Unlike others in the industry, our warranty even covers reimbursement for reasonable repair or replacement charges, including drywall, painting or damage to premises within which the product is installed, due to product leak or failure. It’s just another way we keep our word and quality intact. See our PEX warranty page for full details.

Durability

Our patented PEX formulation allows for us to build a PEX resin blend with the highest stabilizer package in the industry. Coupled with our F1960 fittings, our systems are designed and tested to stand up to the toughest of conditions. Due to this manufacturing flexibility, our products achieve the highest chlorine resistance rating defined by ASTM and up to 6 months of UV resistance.

Strength

Strength in a plumbing system is measured in temperature and pressure resistance, not bending a tube back and forth until it breaks. While all commercially available PEX systems must pass very stringent ASTM requirements, Zurn’s PEX piping goes above and beyond due to our patented higher-strength base resin material and cross-linking process.

Flexibility

Strength and flexibility are a delicate balance when engineering a PEX product. The key is to develop a resin formulation that is high-strength, yet flexible enough to be expanded and bent in a tight radius. Considering that our PEX can be bent as tightly as any PEX on the market and it is expandable, we believe we have achieved the optimal balance.

"Zurn’s Expansion PEX System gives contractors the flexibility to choose between either crimp or expansion fittings to work in tandem with our trusted PEX pipe — ultimately delivering a smarter solution. But it goes well beyond contractor preference, it's less tools and parts to lug around, more intuitive capabilities during the installation process, and serious durability in both engineering and materials. Zurn Expansion PEX helps contractors get the job done right, saving time and money every step of the way."
