PEX-A 3/4 In. Expansion PEX In To X 1/2 In. D FNPT Brass Adapter

The Apollo EPXFA3412 Brass PEX-A Adapter is an essential plumbing fitting designed to connect 3/4 inch PEX-A tubing to 1/2 inch female threaded ports in potable water piping systems. This lead-free brass adapter provides a reliable, durable connection for both new installations and repairs in residential and commercial plumbing applications.

This adapter is a key component when integrating PEX-A systems into existing threaded pipe networks or when building hybrid plumbing configurations.
