Sigma 810027219 1/2 in Street Elbow 150 Lb Malleable Iron

Product Description

The SIGMA 810027219 is a FIG 3104 malleable iron street elbow rated for 150 lb service. It features a male NPT inlet and female NPT outlet, allowing a 90-degree direction change in a threaded pipe run without the need for an additional coupling. The black oxide finish provides basic corrosion resistance for dry and indoor applications. At 1/2 inch nominal size, this fitting is a standard component in low-pressure gas, air, water, and steam distribution systems. Licensed plumbers and pipefitters install this type of fitting in both new construction and repair work.

The 810027219 street elbow is suited for residential and light commercial piping systems where a compact, one-piece direction change is needed at a threaded connection. The MNPT x FNPT configuration lets it thread directly into a pipe end or fitting on one side while accepting a threaded pipe or nipple on the other. Typical applications include natural gas distribution, compressed air lines, and potable or non-potable water systems operating within the 150 lb pressure class rating.

Key Features

• 150 lb pressure class rating for low-pressure gas, air, water, and steam service
• Malleable iron construction provides strength and resistance to impact and vibration
• Black oxide finish for basic corrosion protection in dry or indoor environments
• MNPT x FNPT end style allows direct inline threading without an additional coupling
• 1/2 inch nominal size fits standard NPT pipe threads

Compatibility

Designed as an OEM-style replacement or new-install fitting for 1/2 inch NPT threaded piping systems rated at 150 lb service class.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off and depressurize the supply line before threading or unthreading any fittings. Apply an approved pipe thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten; use a pipe wrench with a backup wrench on adjacent fittings to avoid stressing connected components.
