Sigma 810030809 Fig 3105 Pipe Tee 2 Inch Fnpt 150 Lb

Product Description

The SIGMA 810030809 is a FIG 3105 straight pipe tee designed for threaded pipe assemblies in commercial and industrial piping systems. This fitting features female national pipe taper (FNPT) threads on all three outlets and is rated for 150 lb service. Constructed from malleable iron with a black oxide finish, the 810030809 provides reliable mechanical strength and corrosion resistance in typical black-iron pipe applications. Plumbers, pipefitters, and mechanical contractors install this type of fitting where a full-flow branch connection is required along a straight pipe run.

This tee is suited for use in low-pressure steam, water, gas, and air distribution systems where malleable iron threaded fittings are specified. It is commonly installed in commercial mechanical rooms, industrial process lines, and residential or light commercial gas distribution piping. The FNPT end style allows direct connection to standard NPT-threaded pipe and other NPT-compatible valves, unions, and fittings in the 2 inch nominal pipe size range.

Key Features

• 2 inch nominal pipe size with FNPT threads on all three outlets
• 150 lb pressure class rating suitable for steam, water, gas, and air service
• Malleable iron construction provides impact resistance and ductility compared to cast iron
• Black oxide finish for corrosion inhibition in standard black-pipe installations
• Straight tee configuration delivers equal branch and run flow paths

Compatibility

Designed as an OEM-style replacement and standard-stock fitting for 2 inch nominal NPT threaded pipe systems using 150 lb malleable iron fittings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Shut off and depressurize the piping system completely before removing or installing any fittings. Apply appropriate pipe thread sealant or PTFE tape to the male threads before making up the joint, and tighten to proper engagement using a pipe wrench. Do not over-tighten malleable iron fittings, as the material can crack under excessive torque.
