Midland Industries 700068-0812 Compression Male Adapter

Product Description

The MIDLAND INDUSTRIES 700068-0812 is a lead-free brass male adapter fitting designed to connect 1/2-inch compression tubing to a 3/4-inch male NPTF (MNPTF) threaded port. The compression end uses an 11/16-20 thread and the male pipe end uses a 3/4-14 thread. Rated for service from -40 to 250 degrees F, this adapter is suited for potable water, hydronic, and general plumbing lines where lead-free materials are required by code. Licensed plumbers and pipe fitters are the primary installers. The compact brass body measures 1.65 inches in length and weighs approximately 0.165 pounds.

This adapter is used in residential and light commercial plumbing applications where a compression tubing run must terminate at or transition to a male pipe thread connection. Typical scenarios include supply line connections at valves, fixtures, and equipment ports. It is compatible with copper, aluminum, or plastic tubing on the compression side, making it a versatile transition fitting across multiple tubing materials commonly found in potable water and low-pressure fluid systems.

Key Features

• Lead-free brass construction meets lead-free compliance requirements for potable water applications
• 1/2-inch compression inlet accepts copper, aluminum, or plastic tubing
• 3/4-inch MNPTF outlet threads directly into female pipe thread ports
• Rated from -40 to 250 degrees F for broad service temperature range
• Dual thread specification: 11/16-20 compression x 3/4-14 male pipe
• Compact body at 1.65 inches length for tight-space installations

Compatibility

Designed for use with copper, aluminum, or plastic tubing on the compression end. Suitable as an OEM-style transition fitting wherever a 1/2-inch compression to 3/4-inch MNPTF adapter is required in lead-free plumbing assemblies.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and relieve system pressure before beginning work. Compression fittings require a ferrule and nut assembly seated squarely on the tubing - do not overtighten, as this can crack plastic tubing or deform soft copper. Inspect all connections for leaks after restoring pressure.
