Pex-a 1/2 In. Expansion Pex In To X 1/2 In. D Mpt Brass Adapter

The Apollo EPXMA1212 is a brass barb adapter designed to connect 1/2 inch PEX-A expansion pipe to 1/2 inch male national pipe thread (MNPT) connections. This fitting provides a reliable transition point in plumbing systems where PEX-A tubing meets threaded male ports on valves, manifolds, fittings, or other components. It is commonly used in residential and commercial potable water supply lines as well as hydronic heating and cooling systems.

The barb end of the fitting inserts into PEX-A tubing and is secured using a cold-expansion tool (sold separately), which creates a leak-free seal. The male thread end connects to female threaded ports. This adapter is an essential component when building or expanding PEX-A distribution systems that need to connect to standard threaded fittings and equipment.
