Midland Industries 18207 Brass Compression Adapter 1in

Product Description

The MIDLAND INDUSTRIES 18207 is a brass male adapter fitting that transitions a 1-inch compression connection to a 1-inch male NPTF thread. Designed for use in plumbing and fluid distribution systems, this fitting is suited for connecting copper, aluminum, or thermoplastic tubing to threaded pipe fittings or valves. The 1.38-inch hex provides a solid grip for standard wrenching during installation. The fitting handles a service temperature range of -65 to 250 degrees F, making it appropriate for a wide range of fluid handling and low-pressure applications. Licensed plumbers and pipefitters are the typical installers for this type of compression-to-threaded adapter.

This adapter is commonly used in residential and light commercial plumbing systems where a compression-style tubing run must terminate at a threaded port. Typical applications include water supply lines, refrigeration tubing connections, and pneumatic distribution lines using copper, aluminum, or thermoplastic tube stock. The 2-inch center-to-end dimension provides useful reference for rough-in and space planning in tight installations where fitting clearance matters.

Key Features

• 1-inch compression inlet connects directly to copper, aluminum, or thermoplastic tubing without soldering
• 1-inch male NPTF thread on outlet end provides a pressure-rated threaded connection
• 1.38-inch hex size accommodates standard open-end or adjustable wrenches
• Operating temperature range of -65 to 250 degrees F suits a broad range of service conditions
• 2-inch center-to-end dimension aids in layout and clearance planning
• Brass construction resists corrosion in water and fluid service environments

Compatibility

Designed for use with copper, aluminum, and thermoplastic tubing in compression fitting applications requiring a male NPTF threaded outlet.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC or local plumbing code requirements. Shut off the water or fluid supply and depressurize the line fully before disassembling any existing fittings or installing this adapter. Compression fittings do not require thread sealant on the compression side, but male NPTF threads should be made up with an appropriate thread sealant or tape per the system requirements. Do not overtighten the compression nut, as excessive force can deform the ferrule and compromise the seal.
