6 inch x 4 inch PVC DWV Flush Bushing Fitting x Plastic

6 inch x 4 inch PVC DWV Bushing – High-Performance Reducing Fitting for Drainage Systems

The 6 inch x 4 inch PVC DWV Bushing is engineered for use in drain, waste, and vent (DWV) piping systems, providing a dependable solution for reducing pipe sizes while maintaining flow efficiency. Constructed from rigid polyvinyl chloride (PVC), this fitting offers dimensional stability and corrosion resistance required in non-pressurized gravity drainage applications.

Designed with a spigot x hub configuration, this bushing allows a 6-inch male end to be inserted into a fitting hub, reducing to a 4-inch pipe connection. The transition maintains system integrity while complying with UPC and ASTM standards relevant to DWV installations.

Key Performance Benefits

• ✅ Code-Compliant Sizing – Meets ASTM D2665 and D3311 specifications for DWV systems.
• ✅ High Dimensional Accuracy – Molded with precise tolerances for a tight fit within schedule 40 DWV fittings.
• ✅ Impact-Resistant PVC – Maintains structural performance across a range of ambient temperatures.
• ✅ Long-Term Corrosion Resistance – Will not rust or degrade in contact with soil gases, waste effluent, or moisture.
• ✅ Low-Profile Design – Reducing bushing form allows for compact transitions within confined piping layouts.

Specifications

• Material: Rigid PVC (non-pressure rated)
• Sizes: 6-inch spigot x 4-inch hub
• Connection Type: Spigot x Slip Hub
• Standards: ASTM D2665, D3311; NSF compliant for DWV use

Typical Applications

Used in vertical or horizontal DWV pipe systems for reducing pipe diameter at cleanouts, stack offsets, or fixture branches. Suitable for residential and light commercial construction where non-pressurized waste and vent systems are installed.

Installation Notes

Join using approved PVC solvent cement for DWV fittings. Ensure both mating surfaces are clean and properly primed before assembly. Avoid pressurized applications—this bushing is rated for gravity-fed systems only.

Engineered to perform in accordance with plumbing code and jobsite requirements, the 6 inch x 4 inch PVC DWV Bushing is a proven choice for professionals seeking reliable, space-efficient pipe reduction in drainage systems.
