Midland Industries 00068-0706 Brass Compression Adapter

Product Description

The MIDLAND INDUSTRIES 00068-0706 is a brass compression-to-male NPTF adapter fitting designed to connect compression tubing lines to standard male NPTF threaded ports. It transitions a 7/16-inch compression connection to a 3/8-inch male NPTF thread, with a 5/8-24 by 3/8-18 thread specification and a 0.68-inch hex body for wrench engagement. Rated to 200 psi and suitable for temperatures ranging from -65 to 250 degrees F, this adapter is appropriate for plumbing, HVAC refrigerant piping, and instrumentation applications. Licensed plumbers, HVAC technicians, and industrial pipefitters install this type of fitting in both residential and light commercial service work.

This adapter is intended for use with copper, aluminum, and thermoplastic tubing in compression-style plumbing and gas or fluid distribution systems. The center-to-end measurement of 1.1 inches makes it a compact inline transition fitting suitable for tight installation spaces. It is commonly used when connecting tubing runs to valves, manifolds, or equipment ports that accept 3/8-inch male NPTF threaded connections. Its all-brass construction offers corrosion resistance and reliable sealing performance across a broad range of fluid and gas service conditions.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Shut off and depressurize the line completely before removing or installing compression fittings. Use an appropriately sized open-end or adjustable wrench on the hex body to avoid deforming the fitting body. Follow applicable IPC or IFGC code requirements for the fluid or gas service being connected.
