Know What You’re Buying — Not all PEX F1960 Fittings are the Same

October 2, 2023 | By Uponor

If you’ve been told all PEX F1960 cold expansion fittings are the same because they all conform to the same fitting standard, it’s important to understand there are real differences that can make or break your business.

In truth, not all fittings conforming to the ASTM F1960 standard are the same. Manufacturers and suppliers that claim their fittings are compliant to ASTM F1960 feel that, in their opinion, they meet the standard. However, there is no third-party agency to confirm that compliance.

Certification Difference

Uponor ProPEX fittings are a highly engineered product certified by third-party agencies — NSF and the Canadian Standards Association (CSA) — to ensure the raw materials, manufacturing process, and resulting product accurately meet the ASTM F1960 standard.

In fact, the companies that mold ProPEX EP fittings are partners that are integrated into the codes, helping ensure the highest-quality product. ProPEX fittings also undergo internal quality testing that extends beyond the ASTM F1960 standard requirements to provide customers with the strongest value available on the market.

“It’s important that installers are aware they need to ask for the Uponor brand name from distribution and make sure they are getting what they are paying for in ProPEX fittings,” says Bradfield Craig, director of Marketing at Uponor. “The differences are far beyond just the brand name. Uponor testing on generic F1960 fittings has exposed various manufacturing design and quality inconsistencies, and some fittings can’t even pass the ASTM F1960 standard requirements. This is putting projects at considerable risk for failures and potentially voids the associated system warranties.”

Identifying ProPEX

So, how can you tell if you have a real Uponor ProPEX fitting? The easiest way is to look for the Uponor logo. Other indicators include thicker tube stops and thicker sealing barbs. The thin tube stops on the generic, low-quality F1960 fittings are especially problematic as the expanded PEX pipe can extend past the stops and cause leaks.

If you are purchasing fittings that are not in Uponor packaging and are loose in a bin, be sure to take a close look at each part to ensure you’re getting Uponor ProPEX and not a generic product.
