Sigma 811070812 Malleable Iron Pipe Cross 2 in Fnpt 150 Lb

Product Description

The SIGMA 811070812 is a malleable iron pipe cross fitting designed for use in threaded pipe assemblies where a four-way branch connection is required. Conforming to FIG 3107 pattern, this fitting carries a 150 lb pressure rating and features female national pipe taper (FNPT) end connections on all four outlets. The galvanized finish provides corrosion resistance for use in environments where moisture or mild chemical exposure is a concern. Sized at 2 inches nominal, it is a standard fitting for commercial and industrial piping systems installed by licensed plumbers and pipefitters.

This pipe cross is suited for use in low-pressure water, air, and compatible fluid distribution systems. The FNPT threading allows direct connection to standard NPT-threaded pipe and fittings without adapters. It is commonly installed in mechanical rooms, commercial buildings, and industrial facilities where branch distribution points are required within a threaded malleable iron piping system rated at 150 lb working pressure.

Key Features

• FIG 3107 pattern malleable iron pipe cross with four-way FNPT connections
• 150 lb pressure rating suitable for low-pressure water and air service
• 2 inch nominal size for compatibility with standard 2 inch NPT pipe
• Galvanized finish for added corrosion resistance in wet or damp environments
• Malleable iron construction provides strength and machinability for field modifications if required

Compatibility

Designed as a standard 150 lb malleable iron threaded pipe fitting for use with 2 inch nominal NPT-threaded pipe and fittings in conforming piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with the applicable edition of the International Plumbing Code (IPC) and local jurisdiction requirements. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to male NPT threads before assembly and tighten to proper engagement using pipe wrenches. Do not over-tighten, as malleable iron threads can crack under excessive torque.
