Midland Industries 700068-0706 Compression Adapter Brass

Product Description

The MIDLAND INDUSTRIES 700068-0706 is a lead-free brass compression adapter designed to transition between a 7/16-inch compression connection and a 3/8-inch male NPTF threaded connection. It is used in potable water, plumbing, and fluid-handling applications where a secure, leak-resistant fitting is required between soft tubing and a threaded port. The adapter features a 5/8-24 compression thread and a 3/8-18 NPTF male thread, and it is rated for temperatures from -40 degrees F to 250 degrees F. Its lead-free brass construction meets requirements for use in drinking water systems.

This adapter is suited for residential and light commercial plumbing installations where copper, aluminum, or plastic tubing must connect to a male NPT-threaded fitting or valve. Typical applications include supply line hookups, fixture connections, and inline plumbing assemblies. The compact form factor makes it practical in tight spaces behind fixtures or inside cabinets. It is installed by licensed plumbers and experienced tradespeople working on water supply and distribution systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before removing or installing any compression fitting. Hand-tighten the compression nut onto the tubing, then snug with a wrench - avoid overtightening, which can crack plastic tubing or deform soft copper. Verify the connection is leak-free under system pressure before closing up the work area.
