Copperfit 6C0030 No-hub Coupling 3 Inches

Product Description

The COPPERFIT 6C0030 is a 3-inch no-hub coupling designed for joining cast iron, plastic, or other drain, waste, and vent (DWV) pipe sections without hub-and-spigot fittings. No-hub couplings use a neoprene sleeve and stainless steel band clamps to create a secure, leak-resistant connection in gravity-flow drain systems. This fitting is a standard tool in residential and commercial plumbing rough-in and repair work, installed by licensed plumbers and pipefitters working on DWV piping. At 0.35 pounds, the 6C0030 is lightweight and easy to handle in tight spaces.

This coupling is suited for use in below-grade, on-grade, and above-grade DWV installations where a no-hub mechanical joint is required. Common applications include connecting cast iron sewer pipe sections, repairing damaged hub ends, and transitioning between pipe materials of the same nominal diameter in drain or vent stacks. It is appropriate for both new construction and retrofit service work on residential and light commercial plumbing systems.

Key Features

• 3-inch nominal pipe size for standard DWV drain and vent applications
• No-hub design eliminates the need for hub-and-spigot connections
• Lightweight at 0.35 pounds for easy single-hand positioning during installation
• Compatible with gravity-flow DWV systems in residential and commercial settings

Compatibility

Designed as an OEM-style replacement and standard-fit coupling for 3-inch nominal no-hub DWV piping systems.

Installation Notes

Installation is typically performed by a licensed plumber following local plumbing codes and IPC guidelines for DWV piping. Shut off any upstream flow and ensure the pipe ends are clean, deburred, and properly aligned before sliding the coupling into position. Band clamps should be tightened with a torque-limiting screwdriver to the coupling manufacturer's specification printed on the product. Do not overtighten stainless steel bands, as this can damage the neoprene sleeve and compromise the seal.
