4 in. PVC Schedule-40 DWV Coupling Hub x Hub Drain Waste Vent Pipe Fitting ASTM D2665 NSF

The 4 in. PVC Schedule-40 DWV Coupling Hub x Hub fitting from 247Garden is a high-quality, essential component for joining two sections of 4-inch Schedule-40 drain, waste, and vent (DWV) PVC pipe. Manufactured to meet rigorous ASTM D2665 and NSF standards, this coupling provides a reliable, leak-free connection in non-pressurized DWV systems commonly used in residential, commercial, and industrial plumbing applications.

Featuring dual hub (socket) ends, this coupling allows for solvent-weld connections on both sides, ensuring a strong and permanent bond when used with appropriate PVC primer and cement. Its durable white PVC construction offers excellent resistance to corrosion, chemicals, and environmental wear, guaranteeing long-lasting service life in above-ground and underground installations.

The smooth interior surface promotes efficient flow of waste and vent gases, minimizing the risk of blockages and maintaining system performance. The 4-inch size is widely used for main sewer lines, vent stacks, and other critical sections of DWV piping.
