Charlotte Pipe 146 Cast Iron No Hub 90 Elbow 4 Inches

Product Description

The CHARLOTTE PIPE 146 is a 4-inch cast iron no-hub 90-degree elbow used in drain, waste, and vent (DWV) piping systems. This fitting changes flow direction by 90 degrees and connects to no-hub cast iron pipe and fittings using standard no-hub couplings and clamps. Cast iron construction provides durability and long service life in both above-ground and below-grade installations. Licensed plumbers and pipefitters install this type of fitting in residential and light commercial DWV systems where cast iron is specified for noise reduction, fire resistance, or code compliance.

This elbow is suited for drain, waste, and vent applications in residential and commercial construction. The no-hub design eliminates the need for lead and oakum joints, allowing faster assembly with stainless steel no-hub couplings. It is commonly installed in stack lines, horizontal drain runs, and building drain transitions where a full 90-degree direction change is required. Cast iron DWV systems using no-hub fittings are widely accepted under the International Plumbing Code and Uniform Plumbing Code.

Key Features

• 90-degree sweep changes flow direction in drain, waste, and vent lines
• No-hub end connections accept standard stainless steel coupling clamps
• Cast iron construction offers sound dampening and long-term durability
• Suitable for above-ground and below-grade DWV installations

Compatibility

Designed as an OEM-style replacement and standard component for 4-inch no-hub cast iron DWV piping systems using standard no-hub couplings and clamps.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable plumbing code. Shut off water supply and relieve system pressure before beginning work on any active drain or waste line. No-hub couplings must be torqued to the coupling manufacturer's specified value using a torque-limiting screwdriver or nut driver. Inspect the pipe ends and fitting hub for debris or damage before seating the coupling to ensure a leak-free joint.
