Midland Industries SS5603-12-12-12 Stainless Run Tee 3/4in

Product Description

The MIDLAND INDUSTRIES SS5603-12-12-12 is a 316 stainless steel female pipe run tee designed for high-pressure fluid and gas piping systems. Part of the SS5603 Series, it provides a straight-run flow path with a branch outlet, using a Male NPTF x Female NPTF x Male NPTF connection arrangement. All three ports are sized at 3/4 inch with 3/4-14 thread pitch. This fitting is rated to 7300 psig maximum operating pressure and can handle operating temperatures up to 1000 degrees F, making it suitable for demanding industrial and commercial piping applications. It is installed by licensed plumbers, pipefitters, or mechanical contractors working on high-pressure line assemblies.

This run tee is used in commercial and industrial piping systems where a branch takeoff is needed along the main flow line without interrupting run flow. The female branch port allows inline connection to a threaded pipe segment. Typical applications include process piping, hydraulic lines, compressed air systems, and high-temperature steam or fluid distribution headers where stainless steel corrosion resistance and elevated pressure and temperature ratings are required.

Key Features

• 316 stainless steel construction provides strong corrosion resistance in aggressive media and environments
• Rated to 7300 psig maximum operating pressure for high-pressure system use
• 1000 degrees F maximum operating temperature supports high-heat applications
• Male NPTF x Female NPTF x Male NPTF configuration maintains run flow with branch outlet
• All ports at 3/4 inch with 3/4-14 thread pitch for consistent sizing throughout the fitting
• NPTF threads provide a pressure-tight mechanical seal without sealant on properly mated fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4 inch NPTF threaded piping systems requiring a stainless steel run tee configuration.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with high-pressure threaded piping systems. Shut off and depressurize the line completely before disassembling existing fittings or installing this tee. NPTF threads are designed to seal on thread contact, but consult applicable codes such as ASME B31.3 or local mechanical codes for sealant and assembly requirements on your specific system media. Inspect threads for damage before assembly and do not overtighten, as this can crack fittings or distort thread sealing surfaces.
