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

4 Inch x 2 Inch PVC DWV Flush Bushing – Solvent Weld Reducing Fitting

The 4 inch x 2 inch PVC DWV flush bushing is a solvent weld fitting designed to reduce pipe diameter within drain, waste, and vent systems. Manufactured for compatibility with ASTM-compliant DWV piping, this fitting enables direct insertion into larger hubs or fittings while maintaining a clean, low-profile transition.

Material and Performance Characteristics

Constructed from rigid polyvinyl chloride (PVC), this flush bushing is suitable for non-pressurized gravity flow systems. It supports high dimensional stability and chemical resistance necessary for sanitary drainage systems:

• ✅ Schedule 40 DWV Rated Compatible with standard DWV piping per ASTM D2665 or D1785 specifications.
• ✅ Solvent Weld Connection Designed for installation using PVC primer and cement, ensuring permanent bonding at the joint.
• ✅ Flat-Face Design Allows full insertion with minimal profile, ideal for vertical stack and offset transitions.

Installation Requirements

Ensure pipe and fitting surfaces are clean, dry, and square-cut. Apply approved primer and solvent cement per manufacturer instructions. Insert the bushing fully into the mating hub and allow for appropriate curing time before system testing. Follow all local code requirements and manufacturer-recommended curing schedules.

Application Scope

Flush bushings are commonly used in residential, multi-family, and commercial buildings for reducing larger-diameter DWV lines to smaller branches. Ideal for use in wall cavities, under-slab installations, and confined chase spaces where traditional reducing fittings may extend too far from the hub.

Code and Compliance Information

This fitting meets applicable plumbing codes requiring the use of lead-free, corrosion-resistant, non-metallic materials in DWV systems. It complies with standards for non-pressure sanitary drainage and is suitable for use in both horizontal and vertical configurations.
