Charlotte Pipe Foundry Abs 00107 1600HA Abs Dwv Flush Bushing 4x3

Product Description

The Charlotte Pipe Foundry Co. ABS 00107 1600HA is an ABS DWV flush bushing designed to reduce pipe diameter from 4 inches to 3 inches in drain, waste, and vent systems. The spigot end inserts into a 4-inch hub fitting, while the 3-inch hub end accepts the downstream pipe. This fitting is manufactured from black ABS material and is rated for non-pressure DWV applications only. It is not intended for pressurized water supply lines or systems with elevated chemical exposure. Plumbers and pipefitters install this bushing to transition between pipe sizes within a drain or vent stack without the need for a separate coupling and reducer combination.

This fitting is used in residential and light commercial DWV piping systems where a 4-inch line must step down to a 3-inch continuation. Common install scenarios include branch connections off a main drain stack, closet flange transitions, and vent stack reductions above the highest fixture. It is suited for concealed in-wall, under-slab, and above-ceiling applications where non-pressure ABS DWV piping is specified. This part ships in a package quantity of 30 units per case, making it practical for new construction or tract-housing work.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and local amendments governing ABS DWV piping. Solvent-cement the spigot end into the receiving 4-inch hub and the downstream 3-inch pipe into the hub end using ABS-rated cement and primer per manufacturer instructions. Confirm the system is depressurized and drained before making connections in an existing line. Do not use this fitting in pressure piping, potable water supply, or high-chemical-concentration drain systems.
