Midland Industries 700068-0202 Compression Male Adapter

Product Description

The MIDLAND INDUSTRIES 700068-0202 is a lead-free brass male adapter fitting designed to transition a 1/8 inch compression connection to a 1/8 inch male NPTF (MNPTF) threaded connection. The compression side accepts copper, aluminum, or plastic tubing, while the MNPTF end threads directly into a female NPT port on valves, gauges, or equipment. Thread dimensions are 5/16-24 on the compression side and 1/8-27 on the NPT side. The fitting is rated for temperatures from -40 to 250 degrees F, making it suitable for a wide range of plumbing, HVAC, and instrumentation applications. Licensed plumbers and HVAC technicians install this type of fitting in low-pressure fluid and gas lines where a tool-free tube connection transitions to a threaded port.

This adapter is used in residential and light commercial applications where small-diameter tubing must connect to a threaded component. Typical scenarios include refrigeration sensing lines, instrument tubing runs, fuel lines, and pneumatic control circuits. The lead-free brass construction meets applicable potable-water safety standards, though its small bore size is more commonly encountered in instrument, control, and refrigeration lines than in domestic water supply. It is well-suited for environments requiring corrosion resistance and reliable sealing at moderate pressures and temperatures.

Key Features

• Lead-free brass construction meets lead-free compliance requirements for applicable installations
• 1/8 inch compression inlet accepts copper, aluminum, or plastic tubing without soldering
• 1/8 inch MNPTF outlet threads directly into standard female NPT ports
• Rated from -40 to 250 degrees F for broad temperature compatibility
• Compact profile at approximately 1 inch length for use in tight spaces
• 5/16-24 x 1/8-27 thread specification for precise fitment

Compatibility

Designed for use with copper, aluminum, or plastic tubing on the compression side, and any standard 1/8 inch female NPT threaded port on the outlet side. Suitable as an OEM-style replacement or new-install fitting in compression-to-MNPTF applications.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians following applicable IPC or IFGC guidelines. Shut off system pressure and verify the line is depressurized before disassembling or installing any compression fitting. Hand-tighten the compression nut onto the tubing, then advance with a wrench - do not overtighten, as over-compression can deform tubing and cause leaks. Apply appropriate thread sealant or PTFE tape to the MNPTF threads before threading into the receiving port.
