4 in. PVC Schedule-40 DWV Wye Hub Skew Y-Tee Drain Waste Vent Pipe Fitting ASTM D2665 NSF

The 247Garden 4 in. PVC Schedule-40 DWV Wye Hub Skew Y-Tee is a precision-engineered fitting designed for reliable use in drain, waste, and vent (DWV) systems. Manufactured to meet ASTM D2665 and NSF standards, this hub-to-hub wye fitting provides an efficient, smooth-flow transition between a main 4-inch DWV pipe and a branch pipe at a skewed angle, typically 45 degrees.

Constructed from durable white Schedule-40 PVC, this fitting offers excellent chemical resistance and long-lasting durability in both residential and commercial plumbing installations. Its skewed “Y” design minimizes turbulence and encourages proper drainage flow, reducing the risk of clogs and backups in your plumbing system.

The dual hub (socket) ends allow for solvent-weld installation with standard 4-inch DWV pipe, providing a secure, leak-resistant connection. The 4-inch size is commonly used in sewer lines, vent stacks, and other critical sections of drain and waste piping where a smooth directional change or branch connection is needed.

Key Features:

• Size: 4 inch nominal

• Design: Skew Wye (Y-Tee) with 45° branch angle

• Connection Type: Hub x Hub (Socket x Socket)

• Material: High-quality white Schedule-40 PVC (Polyvinyl Chloride)

• Standards: ASTM D2665 and NSF certified for DWV applications

• Application: For non-pressurized drain, waste, and vent piping systems

• Flow Efficiency: Smooth internal design reduces flow resistance and buildup

• Durability: Resistant to corrosion, chemicals, and environmental factors

• Installation: Solvent weld both ends with PVC primer and cement for permanent seal

Typical Applications:

• Connecting a branch drain line to a main 4-inch DWV line

• Transition points in residential, commercial, and industrial plumbing systems
