High-Purity PVDF Pipe Fittings for Corrosive Chemicals
Made of PVDF that’s finished to a 12 Ra smoothness, these fittings handle some of the harshest chemicals without leaching contaminants into your line. They won’t accumulate particles and are easy to clean, thanks to their smoothness. Comparable to Kynar, these fittings handle most organic solvents that would dissolve CPVC, and chlorine or nitric acid that would weaken polypropylene. You can use them at higher temperatures than CPVC and polypropylene. These fittings meet UL 94 V-0 and FM standards for flame retardance. They’re also FDA compliant for direct contact with food, and they meet ASTM requirements for dimensions and tolerances.
Connect them to pipe with socket fusion welding for a strong, permanent bond. Use a socket fusion tool with a heater bushing (sold separately) that matches your pipe size.
