Apollo 1/2 in. Brass ExpansionPEX Coupling

Apollo ExpansionPEX couplings are manufactured using lead-free, dezincification-resistant brass engineered for superior durability and corrosion resistance. Exclusively designed for use with PEX-A piping, these fittings provide a full-flow design that ensures fast and efficient fluid delivery across hot and cold domestic potable water as well as hydronic heating and cooling systems. These reliable expansion fittings require a cold expansion tool for secure installation, ensuring tight connections every time without the need for go/no-go gauges. Designed to integrate seamlessly with standard PEX-A expansion systems, this coupling delivers high-performance reliability for residential and commercial plumbing applications.
