Midland Industries 700068-0806 Compression Adapter

Product Description

The MIDLAND INDUSTRIES 700068-0806 is a lead-free brass male adapter fitting designed to connect 1/2-inch compression tubing to a 3/8-inch male NPTF threaded port. The compression side uses an 11/16-20 thread and the male threaded end is 3/8-18, providing a reliable, leak-resistant joint without soldering. Built from lead-free brass, this adapter meets drinking water safety requirements and is rated for temperatures from -40 to 250 degrees F. It is installed by licensed plumbers and experienced pipe fitters in potable water, refrigeration, and general fluid-handling applications where a transition from compression tubing to a threaded male fitting is required.

This adapter is suited for residential and light commercial plumbing installations. It is commonly used in supply line connections, under-sink shutoff configurations, and equipment hookups where copper, aluminum, or plastic tubing terminates at a threaded male port. The compact form factor makes it practical in tight spaces such as cabinet interiors, wall cavities, and equipment panels where clearance is limited.

Installation Notes

Installation is performed by a licensed plumber or qualified pipe fitter. Shut off the water supply and relieve system pressure completely before disassembling any existing fittings or installing this adapter. Hand-tighten the compression nut onto the tubing before applying tool torque to avoid cross-threading. Verify that the mating female port is clean, undamaged, and free of debris before making the threaded connection; apply thread sealant appropriate for the service fluid per local plumbing code requirements.
