About this item

• Durable PPSU Construction: Made from high-performance Polyphenylsulfone (PPSU), these PEX-A expansion fittings offer excellent resistance to corrosion, scale, and chlorine, making them a reliable alternative to brass fittings in reverse osmosis (RO) and chlorinated water systems.
• PEX-A Expansion Connection: Designed to connect 3/4" PEX-A tubing to a 3/4" Male NPT threaded connection using an expansion ring. PEX-A expansion systems provide a secure, leak-resistant connection while accommodating pressure and temperature changes.
• Expansion System Required: Compatible with PEX-A expansion systems only. Installation requires a PEX expansion tool and ASTM F1960 expansion rings (sold separately). Not compatible with stainless steel clamp or copper crimp ring systems.
• Wide Range of Applications: Ideal for residential hot and cold potable water distribution, radiant floor heating, and direct burial applications, including concrete. Compatible with all major brands of PEX-A pipe and expansion systems.
• Fast & Secure Installation: Expansion fittings create a strong, permanent connection by allowing the expanded tubing and ring to contract tightly around the fitting. No glue, solder, or crimping is required.
• Meets Industry Standards: Manufactured to meet ASTM F1960 and ASTM F877 standards for quality, safety, and reliable performance in PEX-A plumbing systems.
