Midland Industries 700068-0408 Compression Adapter Brass

Product Description

The MIDLAND INDUSTRIES 700068-0408 is a lead-free brass compression adapter designed to transition a 1/4-inch compression connection to a 1/2-inch male national pipe thread fuel (MNPTF) fitting. Built for use in plumbing and refrigeration piping systems, this adapter provides a reliable, leak-resistant joint without soldering. The 7/16-24 compression thread mates with the 1/4-inch tubing end, while the 1/2-14 NPT thread engages the male pipe side. Rated for service from -40 to 250 degrees F, it suits a broad range of residential and light commercial plumbing applications where lead-free compliance is required by code.

This adapter is intended for use with copper, aluminum, or plastic tubing in potable water, hydronic, and light-duty gas or refrigeration lines where a compression-to-MNPTF transition is needed. It is commonly installed by licensed plumbers during fixture connections, appliance hookups, or retrofit work requiring a quick, tool-assisted compression joint at a threaded pipe outlet.

Installation Notes

Installation is performed by a licensed plumber. Shut off the water supply and depressurize the line before beginning work. Ensure tubing is cut cleanly and deburred before seating into the compression fitting to prevent leaks. Apply thread sealant or PTFE tape to the MNPTF threads as appropriate for the application, following local plumbing code requirements.
