Midland Industries 30392 Straight Adapter Brass Fitting

Product Description

The MIDLAND INDUSTRIES 30392 is a straight brass adapter fitting designed to connect a 3/8 inch push-on hose barb to a 3/4 inch male national pipe taper fuel (MNPTF) threaded port. Built from brass for corrosion resistance and durability, this adapter is rated to 150 psi and measures 1.97 inches in overall length with a 1.06 inch hex for wrench engagement. The 3/4-14 thread pitch ensures a secure, leak-resistant connection to standard NPT fittings. Plumbers, HVAC technicians, and fluid system installers use this fitting in low-pressure gas, fuel, or fluid transfer applications requiring a transition from push-on hose to a threaded male port.

This adapter is suited for residential and light commercial plumbing, HVAC, and fluid handling installations where a push-on hose barb connection must transition to a standard 3/4 inch male NPT threaded fitting. The push-on barb end accommodates 3/8 inch ID hose, making it a practical choice for fuel lines, coolant lines, and similar low-pressure fluid circuits. With a compact profile and a 0.92 inch barb length, it fits in tight installations without requiring additional clearance.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Shut off fluid or gas supply and depressurize the line before installing or removing any fitting. Apply thread sealant or PTFE tape to the MNPTF threads as required by local plumbing codes before tightening. Do not overtighten brass fittings, as brass threads can be damaged by excessive torque.
