Asc Engineered Solutions 1D.BDLTL Long Turn 90 Deg Dwv Elbow

Product Description

The ASC Engineered Solutions 1D.BDLTL is a long-turn 90-degree drainage, waste, and vent (DWV) elbow fitting manufactured from cast iron with a black finish. Rated at 125 lb, this fitting uses NPS end connections and is sized at 1-1/2 inches nominal. The long-turn radius reduces flow restriction compared to standard short-turn elbows, making it a preferred choice in drain and waste lines where flow efficiency and code compliance matter. Licensed plumbers and pipefitters install this fitting in residential and light commercial drain-waste-vent systems. Domestic manufacture supports projects with material-of-origin requirements.

This fitting is suited for gravity-flow DWV applications in residential and commercial plumbing systems. The 1-1/2-inch nominal size is common in branch drain lines serving lavatories, utility sinks, and similar fixtures. The long-turn configuration is frequently required by plumbing codes where abrupt direction changes could restrict drainage or create debris buildup. It is installed in horizontal-to-vertical and horizontal-to-horizontal transitions within DWV piping assemblies.

Key Features

• Long-turn 90-degree bend reduces flow restriction in drain and waste lines
• Cast iron construction rated at 125 lb for durability in DWV service
• Black finish suitable for exposed or concealed installation
• NPS end style for standard threaded pipe connections
• 1-1/2-inch nominal size fits common branch drain applications

Compatibility

Designed as an OEM-style replacement fitting for 1-1/2-inch nominal NPS threaded cast iron DWV piping systems in residential and commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and ensure the drain line is clear and depressurized before beginning work. Use appropriate pipe thread sealant or tape rated for iron pipe fittings on all NPS threaded connections. Inspect threads on both the fitting and mating pipe for damage before assembly.
