1-1/2 inch x 1-1/4 inch PVC DWV Flush Bushing Fitting x Plastic

1-1/2 inch x 1-1/4 inch PVC DWV Flush Bushing – Code-Compliant Transition for Drainage Systems

The 1-1/2 inch x 1-1/4 inch PVC DWV Flush Bushing provides a compact and efficient method for size reduction in non-pressurized drain, waste, and vent (DWV) systems. Fabricated for compatibility with Schedule 40 PVC components, this fitting ensures reliable dimensional transition in confined plumbing assemblies.

Manufactured to industry specifications, the flush design allows insertion into fittings without protrusion, supporting system clearance requirements and reducing the likelihood of misalignment. Designed for long-term exposure to typical DWV environments, the material exhibits strong resistance to biological and chemical degradation.

Key Performance Characteristics

• ✅ Injection-Molded Precision – Maintains tight dimensional tolerances for proper engagement and seal integrity.
• ✅ Corrosion-Resistant PVC – Suitable for DWV applications where prolonged moisture contact and chemical exposure occur.
• ✅ Low-Profile Interface – Flush design allows unobtrusive installation into hubs and fittings without extending past mating surfaces.
• ✅ Code-Compliant Composition – Fabricated with lead-free materials in accordance with applicable plumbing regulations.
• ✅ Reduced Failure Risk – Designed to minimize separation or distortion under thermal and mechanical stresses in residential and light commercial systems.

Installation Guidance

This flush bushing is intended for use in solvent-cemented joints. Installers should follow ASTM D2855 procedures, applying primer and solvent cement appropriate for PVC materials. Ensure components are free from contaminants prior to assembly and maintain insertion pressure during set time to promote full bonding. Proper curing time should be observed based on ambient temperature and pipe diameter.

Typical Applications

Commonly used to reduce pipe size within branch lines of DWV networks, this bushing is often placed inside tees, wyes, or elbows in both new construction and retrofit work. It is particularly suited for vertical and horizontal pipe runs located in wall cavities, floor systems, or mechanical chases where spatial efficiency is critical.

Regulatory Note

Products intended for use in potable water or residential drainage systems must meet current low-lead and material safety standards. This fitting complies with applicable code requirements for lead-free content and is suitable for use in systems subject to inspection under IPC and UPC jurisdictions.
