Charlotte Pipe Abs 00102 1400HA Abs Dwv Reducer Coupling 4x3

Product Description

The CHARLOTTE PIPE FOUNDRY CO. ABS 00102 1400HA is an ABS DWV reducer coupling in a hub-by-hub configuration, designed to join two lengths of drain, waste, and vent pipe while stepping down from a 4-inch pipe to a 3-inch pipe. Made from black ABS material, this fitting is intended for non-pressure gravity-flow applications in residential and light commercial plumbing systems. It offers a straightforward solvent-weld connection at both hubs, making it a standard choice for licensed plumbers routing DWV lines through walls, floors, and chases. The fitting ships in packages of 20 units, making it suitable for larger jobs or restocking supply.

This coupling is used in non-pressure drain, waste, and vent piping systems where a reduction in pipe diameter is required mid-run. Typical install scenarios include reducing a 4-inch building drain or soil stack to a 3-inch branch line. The fitting is appropriate for residential new construction, remodels, and commercial rough-in work governed by the International Plumbing Code or local adopted equivalents. Its black ABS construction is standard for above-slab DWV installations in many jurisdictions.

Key Features

• Hub x hub ends accept solvent-weld connections on both sides for a secure, leak-resistant joint
• Reduces from 4 inches to 3 inches in a single fitting, eliminating the need for multiple adapters
• ABS black material suited for non-pressure DWV service
• For use in drain, waste, and vent systems only — not rated for pressure applications
• Packaged in quantities of 20 units per package for jobsite efficiency

Compatibility

Designed as an OEM-style ABS DWV fitting compatible with standard 4-inch and 3-inch ABS DWV pipe systems used in residential and commercial non-pressure drain, waste, and vent installations.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code or the locally adopted plumbing code. Shut off water supply and ensure the drain line is dry and clear before cutting into an existing system. Clean and dry both pipe ends and hub sockets, apply ABS solvent cement evenly, and seat the pipe with a quarter-turn twist to ensure full contact. Do not use this fitting in pressurized water supply lines or outdoor UV-exposed applications where ABS is not code-approved.
