Midland Industries 16009 Double Compression Break-away Nut

Product Description

The MIDLAND INDUSTRIES 16009 is a double compression sleeve break-away nut designed for secure, leak-resistant tubing connections in plumbing, HVAC, and instrumentation applications. The fitting uses a threaded 1/8 in connection size with a 5/16-24 thread specification and features a 0.31 in hex profile for standard wrench engagement. Constructed from brass, the 16009 delivers reliable performance across a wide operating temperature range of -65 to 250 degrees F and is rated to 500 psi. Plumbers, HVAC technicians, and instrumentation specialists install this type of fitting where tubing must be connected and periodically removed without damaging the line.

This break-away nut is suited for residential and light commercial applications involving small-diameter tubing runs. It is compatible with aluminum, copper, and plastic tubing, making it a versatile choice for refrigerant lines, pneumatic control circuits, fuel systems, and instrument tubing. The double compression design creates a two-stage grip on the tubing wall, providing a more secure seal than single-ferrule fittings in vibration-prone or high-cycle environments.

Compatibility

Designed for use with aluminum, copper, and plastic tubing in double compression fitting assemblies requiring a 1/8 in threaded break-away nut.

Installation Notes

This fitting is typically installed by licensed plumbers, HVAC technicians, or instrumentation mechanics. Shut off all pressure to the tubing system before disassembly or installation. Use a properly sized wrench on the 0.31 in hex to avoid rounding the fitting. Do not overtighten, as the brass body can be damaged; hand-tighten and follow with a fractional turn per standard compression fitting practice.
