Frequently Asked Questions
How does a cold expansion collar work with PEX plumbing?
The collar slides over the end of PEX-A tubing before expansion. When the pipe and collar are expanded and the fitting is inserted, the natural memory of PEX-A causes the material to shrink back down, forming a secure mechanical seal capable of withstanding rated system pressure.
What is the difference between PEX-A expansion rings and crimp rings?
PEX-A expansion rings require an expansion tool to stretch the pipe and ring before inserting the fitting. Crimp rings use a crimping tool to compress a metal band over the pipe. Expansion systems are compatible only with PEX-A tubing, while crimp systems are typically used with PEX-A, PEX-B, or PEX-C under different ASTM standards.
Is this cold expansion PEX collar safe for drinking water?
Yes. The collar is certified to NSF/ANSI 61 and NSF/ANSI 372 standards, confirming it is lead-free and safe for potable drinking water systems.
Can this ASTM F1960 PEX collar be used with PEX-B tubing?
No. ASTM F1960 expansion collars are compatible only with PEX-A tubing. PEX-B and PEX-C do not have the required thermal memory for safe cold expansion connections.
Is a special tool required to install this PEX expansion collar?
Yes. Installation requires a dedicated PEX expansion tool, either manual or battery-powered. Standard crimp or clamp tools are not compatible with cold expansion systems.
Does the collar restrict water flow?
No. Cold expansion systems maintain a larger internal diameter compared to insert-style crimp systems, helping reduce flow restriction and maintain optimal water performance.
