The MIDLAND INDUSTRIES 43251 is a bronze tee fitting used to split or combine flow in threaded pipe systems. All three ports are 1/4 in female pipe thread (FPT), sized at 1/4-18 thread. The fitting carries an Extra Heavy (XH) schedule rating and is rated for 250 psi service pressure. Constructed from bronze, it resists corrosion in both wet and dry service environments. Plumbers, pipefitters, and mechanical contractors install this type of fitting in low- to medium-pressure gas, water, and fluid distribution lines where a branch connection is required at a common port size.
This fitting is suited for residential and light commercial plumbing, HVAC auxiliary piping, pneumatic lines, and fuel gas distribution systems where all three branch connections share the same 1/4 in FPT port size. The extra heavy wall construction makes it appropriate for higher-pressure applications that exceed the demands of standard-weight fittings. It is sold individually and is a direct-thread-in fitting requiring no special tooling beyond standard pipe wrenches and thread sealant.
Designed as an OEM-style replacement or new-installation fitting for threaded bronze pipe systems using 1/4 in FPT connections in extra heavy service classifications.
Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC requirements for threaded fittings. Shut off and depressurize the line before removing any existing fitting. Apply a listed pipe thread sealant or PTFE tape to the male threads before making up the joint. Do not overtighten; use a backup wrench on adjacent fittings to avoid stressing the pipe.
