Mr Pex 4343210 EK32 1 Inch Npt Loop Adapter Fitting 2-pack

Product Description

The MR PEX 4343210 is a brass loop adapter fitting assembly that connects EK32 manifolds to 1-inch NPT threaded ports in hydronic and radiant heating systems. Sold in a bag of two assemblies, this fitting provides a reliable transition between EK32-style manifold connections and standard 1-inch NPT supply and return lines. Constructed from brass, the fitting is rated for a maximum working pressure of 200 psi and a maximum temperature of 200 degrees F, making it suitable for the demands of closed-loop heating applications. Licensed plumbers and radiant heating installers are the primary trade professionals who work with this component.

This fitting assembly is designed for use as an accessory in PEX-based heating systems, including residential and light commercial radiant floor heating and hydronic distribution loops. It serves as the interface point where an EK32 manifold connects to the larger NPT-threaded supply and return piping of the system. The 2-pack quantity is well suited for a single manifold installation requiring both supply and return connections.
