Sigma 811027606 Fig 3104 Street Elbow 1 in 150 Lb Galvanized

Product Description

The SIGMA 811027606 is a FIG 3104 galvanized malleable iron street elbow designed for threaded pipe assemblies in plumbing, mechanical, and industrial piping systems. With a 1-inch nominal size and a male NPT by female NPT (MNPT x FNPT) end configuration, this fitting allows a direction change directly off a threaded male connection without requiring an additional coupling. Rated at 150 lb, it suits standard pressure service in water, air, and gas distribution lines. Licensed plumbers and pipefitters typically specify this fitting for above-ground and in-wall installations where a compact 90-degree turn is required in a threaded iron system.

This street elbow is suited for residential and light commercial piping applications where galvanized malleable iron fittings are called for by code or preference. The MNPT x FNPT layout makes it practical for connecting directly to valve outlets, nipples, or other threaded fittings that terminate in a male thread. It is a standard FIG 3104 pattern, which is a widely recognized dimension series in the malleable iron fitting trade.

Key Features

• FIG 3104 street elbow configuration for compact 90-degree direction changes in threaded systems
• 1-inch nominal size with MNPT x FNPT end style for direct male-to-female threaded connections
• 150 lb pressure rating suitable for water, air, and gas service at standard working pressures
• Malleable iron construction provides strength and resistance to mechanical stress in threaded assemblies
• Galvanized finish offers corrosion resistance for extended service life in typical piping environments

Compatibility

Designed as an OEM-style replacement and standard-service fitting for 1-inch nominal threaded iron piping systems using 150 lb malleable iron fittings conforming to the FIG 3104 pattern.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable plumbing codes such as the IPC or IFGC. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly and tighten to hand-tight plus the appropriate number of turns using a pipe wrench. Do not overtighten malleable iron fittings, as the material can crack under excessive torque.
