Midland Industries 18195 Brass Compression Adapter

Product Description

The MIDLAND INDUSTRIES 18195 is a straight brass compression adapter designed to connect 1/2-inch compression tubing to a 1/2-inch male NPTF threaded port. The fitting is machined from brass and rated for pressures up to 200 psi with a temperature range of -65 to 250 degrees F. It features an 11/16-20 x 1/2-14 thread specification and a 0.87-inch hex body for standard wrench engagement. The center-to-end measurement is 1.41 inches. Plumbers, HVAC technicians, and pipefitters install this fitting when transitioning from a compression tube run to a male NPTF threaded connection point.

This adapter is suited for residential and light commercial plumbing, HVAC refrigerant line accessories, and utility piping applications where a reliable compression-to-threaded transition is required. It is compatible with copper, aluminum, and thermoplastic tubing. The brass construction makes it appropriate for use in water supply, fuel gas, and instrumentation lines where corrosion resistance and pressure integrity are priorities.

Compatibility

Compatible with copper, aluminum, and thermoplastic tubing in compression-style plumbing and HVAC applications. Designed as an OEM-style brass compression adapter for 1/2-inch tubing systems terminating at a male NPTF threaded connection.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians. Shut off the water supply or system pressure and relieve line pressure completely before disassembly or fitting installation. Compression fittings require proper tube squareness and a clean cut end - do not overtighten, as brass compression fittings can crack or deform the ferrule. Refer to local plumbing codes and IPC guidelines for approved materials and pressure ratings in your jurisdiction.
