The ASC Engineered Solutions 20MXD.WFMJF is a brass mechanical joint fitting with female NPT (FNPT) end connections. It transitions between a 3/4 inch and 1/2 inch nominal pipe size and measures 1.484 inches in length. The fitting is constructed from brass, offering reliable corrosion resistance in both water and gas distribution applications. It is intended for use by licensed plumbers and pipefitters working on residential and light commercial piping systems where a threaded mechanical joint connection is required at a reducing size change.
This fitting is suited for potable water supply lines, hydronic heating systems, and general plumbing distribution piping where a 3/4 inch to 1/2 inch FNPT reducing connection is needed. The domestic manufacture designation indicates the fitting meets applicable domestic production standards. It is a compact, single-piece fitting appropriate for tight installation spaces where a low-profile transition is required.
Designed as an OEM-style replacement or new-installation fitting for residential and light commercial plumbing systems using standard NPT threaded pipe connections.
Installation should be performed by a licensed plumber in accordance with the applicable edition of the International Plumbing Code (IPC) and local amendments. Shut off water supply and relieve system pressure before removing or installing any threaded fitting. Apply thread sealant tape or pipe compound rated for the intended service to all male threads before assembly. Do not overtighten brass fittings, as this can crack the fitting body.
