Asc Engineered Solutions 311019400 Street 90 Elbow 1-1/4x1 in

Product Description

The ASC ENGINEERED SOLUTIONS 311019400 is a galvanized malleable iron street 90 elbow with a 1-1/4 inch female pipe thread (FPT) inlet and a 1 inch male pipe thread (MPT) outlet. This reducing street ell makes a 90-degree directional change in a threaded piping system while also stepping down the pipe size in a single fitting, eliminating the need for a separate reducer. The galvanized coating provides corrosion resistance for use in water, gas, and general-purpose piping applications. At 0.89 pounds, it is a compact, domestically produced fitting suited for both new construction and repair work. Licensed plumbers and pipefitters are the typical installers in commercial and residential settings.

This fitting is used wherever a threaded piping run requires a 90-degree turn combined with a one-size reduction from 1-1/4 inch to 1 inch pipe. Common install scenarios include supply and distribution piping in plumbing systems, compressed air lines, and low-pressure gas piping. The street configuration allows the MPT end to thread directly into another fitting, a valve, or a tee without requiring a nipple, saving space in tight rough-in areas. It is suitable for above-grade and indoor applications where threaded malleable iron fittings are specified.

Key Features

• Street elbow design: MPT outlet threads directly into adjacent fittings without an intermediate nipple
• Reducing configuration transitions from 1-1/4 inch to 1 inch pipe in a single fitting
• 90-degree angle for right-angle directional changes in threaded piping runs
• Galvanized coating for corrosion resistance in water and general-service piping
• Malleable iron construction provides durability and resistance to cracking under stress
• Domestically produced fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch by 1 inch threaded malleable iron piping systems using standard NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing and mechanical codes such as the IPC or IFGC. Shut off and depressurize the piping system completely before cutting into or disassembling any threaded connections. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly and tighten fittings to hand-tight plus the number of turns recommended by the sealant manufacturer. Do not over-torque malleable iron fittings, as cracking can occur.
