Midland Industries 20705N Straight Male Adapter Fitting

Product Description

The MIDLAND INDUSTRIES 20705N is a straight male adapter fitting designed for connecting 12 mm push-to-connect tubing to a 1/2-inch male global thread port. Constructed from nickel-plated brass, this metric male connector delivers reliable sealing performance in pneumatic and fluid transfer applications. It is rated to 290 psi and handles temperatures from -4 to 176 degrees F. The push-to-connect end accepts 12 mm OD tubing without additional tools, while the threaded end uses a global thread profile compatible with a wide range of ported components. HVAC technicians, plumbers, and industrial service pros install this type of fitting where metric tubing must interface with standard threaded ports.

This fitting is suited for use in compressed air lines, pneumatic control circuits, and fluid handling systems where a metric push-to-connect to male threaded transition is required. It is commonly installed in light commercial and industrial equipment, as well as HVAC control systems that use metric tubing with globally threaded valve or manifold ports. The 0.78-inch hex allows installation with a standard open-end or combination wrench.

Compatibility

Designed as a metric male connector for push-to-connect pneumatic and fluid systems requiring a 12 mm OD tube connection to a 1/2-inch male global thread port.

Installation Notes

Shut off all system pressure and depressurize the line before installing or removing push-to-connect fittings. Insert tubing fully into the push-to-connect end until it seats against the internal stop to ensure a leak-free connection. Thread the male end into the receiving port by hand first, then tighten with a wrench to the port material manufacturer recommendations. Verify the full assembly is pressure-tested before returning the system to service.
