Nibco I042500 Dwv 45 Degree Elbow 1-1/4 in Abs

Product Description

The NIBCO I042500 is a 45-degree elbow fitting for drain, waste, and vent (DWV) piping systems. Molded from acrylonitrile butadiene styrene (ABS), it provides a reliable directional change in gravity-flow drain lines. The hub-by-hub end connections accept standard ABS pipe on both ends, bonded with solvent cement. Rated for service from -40 degrees F to 180 degrees F, this fitting suits a broad range of residential and light commercial plumbing environments. It weighs 0.11 pounds and is manufactured under ISO 9001:2008 quality standards. Licensed plumbers and pipefitters install this fitting during rough-in or repair work on DWV systems.

This fitting is used in residential and light commercial DWV piping to change flow direction at a 45-degree angle, reducing the abruptness of the turn compared to a 90-degree elbow. Common applications include branch drain lines, horizontal-to-horizontal transitions, and stack offsets where a gradual change of direction is required by code. The 1-1/4-inch size is typical for lavatory sink drain lines and similar fixture connections. It is suitable for use in concealed or exposed drain piping where ABS plastic is an approved material.

Key Features

• 45-degree angle provides a gradual directional change in DWV drain lines
• ABS construction resists corrosion and chemical exposure common in drain service
• Hub x hub end connections accept standard 1-1/4-inch ABS pipe with solvent cement
• Rated from -40 degrees F to 180 degrees F for broad temperature compatibility
• Manufactured under ISO 9001:2008 quality management standards
• Lightweight at 0.11 pounds, simplifying handling during rough-in

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4-inch ABS DWV piping systems where solvent-cement hub connections are specified.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local codes governing ABS DWV piping. Clean and deburr pipe ends before applying ABS solvent cement; follow cement manufacturer dwell and cure times before pressurizing or putting the line into service. Ensure proper slope and support of horizontal drain runs per code requirements. Do not use this fitting on pressurized supply lines or systems outside its rated temperature range.
