Legend Valve LEGE-303-420 No Hub Coupling 3 Inches

Product Description

The LEGEND VALVE LEGE-303-420 is a 3-inch heavy duty no hub coupling designed for joining cast iron soil pipe and fittings without threaded or hubbed connections. It uses a stainless steel shielded band and neoprene gasket to create a leak-resistant mechanical joint in drain, waste, and vent (DWV) systems. This coupling meets ASTM and CISPI standards, making it appropriate for residential and light commercial plumbing installations. Licensed plumbers and pipefitters are the primary installers for this type of fitting.

No hub couplings in this size range are commonly used in below-grade and above-grade DWV piping systems where cast iron pipe sections are joined or repaired. The heavy duty designation indicates a reinforced shield construction intended for higher-stress or longer-span installations where standard couplings may be insufficient. This fitting is suited for new construction and retrofit work on 3-inch drain and vent lines.

Key Features

• Heavy duty construction for reinforced mechanical joining of no hub cast iron pipe
• 3-inch pipe size for standard DWV drain and vent applications
• Meets ASTM A 240, ASTM C1540, ASTM C564-11, B602-10, B70-06, and CISPI Standard 310-11
• Neoprene gasket design provides a leak-resistant seal without threading or hubbing
• Stainless steel banded shield for corrosion resistance and structural integrity

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 3-inch no hub cast iron soil pipe and fittings in residential and commercial DWV systems meeting CISPI 310-11 requirements.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water supply and ensure the pipe section is clean and free of burrs or debris before seating the neoprene gasket. Torque the band clamps evenly using a torque-limiting driver appropriate for no hub couplings per CISPI 310 guidelines. Do not over-torque, as this can damage the gasket and compromise the seal.
