3 inch x 2 inch PVC DWV Flush Bushing Fitting x Plastic

3 Inch x 2 Inch PVC DWV Flush Bushing – Spigot x Hub

The 3" x 2" PVC DWV flush bushing is engineered for reducing DWV system pipe sizes in gravity flow drainage, waste, and vent applications. This fitting provides a smooth, compact transition from a 3-inch hub to a 2-inch spigot, ensuring flow efficiency and compliance with code-regulated installations.

Engineered for Performance

Designed in accordance with ASTM D2665 and D3311 standards, this flush bushing supports consistent dimensional accuracy and long-term mechanical integrity in PVC drainage systems:

• ✅ Schedule 40 PVC – Durable construction suitable for above- or below-grade DWV applications.
• ✅ Flush Profile – Compact form factor eliminates protrusion into the flow path, reducing turbulence and debris accumulation.
• ✅ Solvent-Weld Connections – Spigot end fits directly into 3" fitting hubs; 2" hub receives pipe insert per standard solvent-welding techniques.

Contractor-Focused Benefits

Suitable for new construction and retrofit scenarios, this flush bushing streamlines installation while maintaining compliance with applicable plumbing codes:

• ✅ Code-Compliant Sizing – Meets dimensional and material standards under IPC, UPC, and CSA B181.2 for non-pressurized drainage systems.
• ✅ Space-Efficient Installation – Low-profile design minimizes interference with adjacent system components in confined areas such as wall cavities or underfloor assemblies.
• ✅ Leak-Resistant Joints – Designed to form uniform solvent-welded connections when installed using appropriate primer and cement.

Installation Parameters

Use primer and solvent cement approved for PVC systems per ASTM D2564. Ensure full insertion depth and uniform solvent application for a permanent, leak-free seal. Flush bushings are not designed for pressurized systems or hot water distribution—intended strictly for DWV systems.

Applications

Typically used in residential and light commercial plumbing where a 3" drain line must transition to a 2" branch, such as lavatory, laundry, or shower drains. Common in fixture wet venting and stack offsets where space and flow alignment are critical.

Regulatory Note

This component is manufactured from lead-free PVC resin in compliance with current DWV system code requirements. It is suitable for use in systems subject to third-party inspection and testing.

The 3 Inch x 2 Inch PVC DWV Flush Bushing provides a reliable, compact solution for pipe size transitions within non-pressurized drainage systems. Built for long-term use and code compliance, it ensures flow efficiency and installation consistency for high-performance DWV layouts.
