The MIDLAND INDUSTRIES 34215 is a rigid male adapter fitting designed to connect a 1/2-inch hose barb to a 1/4-inch male NPT port. Constructed from plated steel with a 1/4-18 NPT thread specification, this forged steel fitting provides a secure, leak-resistant transition between a barbed hose connection and a threaded pipe fitting. It is suited for use in plumbing, pneumatic, and fluid transfer applications where a reliable barb-to-NPT conversion is required. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers of this type of hardware.
This adapter is commonly used in residential and light commercial plumbing and fluid systems where a flexible hose must terminate at a threaded male NPT port. The 1/2-inch hose barb side accepts standard 1/2-inch inside diameter hose, while the 1/4-inch male NPT end threads directly into a female NPT-tapped port on valves, manifolds, tanks, or equipment housings. Its rigid forged steel construction makes it appropriate for moderate-pressure service lines, compressed air systems, and water or oil transfer lines.
Designed as an OEM-style replacement or new-installation fitting for systems requiring a 1/2-inch hose barb to 1/4-inch male NPT transition in plumbing, pneumatic, or fluid transfer assemblies.
Installation should be performed by a qualified plumber, pipefitter, or HVAC technician in accordance with applicable IPC or local plumbing codes. Shut off fluid or air supply and depressurize the line fully before installing or removing any fitting. Apply thread sealant tape or pipe compound to the male NPT threads before threading into the female port. Do not overtighten, as this is a steel fitting threaded into a female port that may be softer material.
