1/2 In. Expansion PEX In To X 3/4 In. D Barb Brass Straight Coupling

The Apollo EPXC1234 is a lead-free brass reducing coupling designed to connect 1/2-inch PEX pipe to 3/4-inch PEX pipe in a single fitting. This coupling is an essential component for PEX plumbing and hydronic heating systems, providing a reliable transition between different pipe sizes.

Constructed from dezincification-resistant brass, this coupling is suitable for both potable drinking water systems and closed-loop hydronic heating applications. The barbed design works with industry-standard connection methods, making it compatible with copper crimp rings, stainless steel pinch clamps, and stainless steel crimp sleeves. With a 200 psi pressure rating, this fitting meets the demands of typical water and heating system installations.

Features and Benefits
