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

2 inch x 1-1/4 inch PVC DWV Reducing Bushing – Socket Fitting for Gravity Drainage Systems

The 2 inch x 1-1/4 inch PVC DWV Reducing Bushing is a molded transition fitting used to reduce pipe size within non-pressurized drain, waste, and vent (DWV) systems. Constructed from rigid polyvinyl chloride (PVC), this fitting is engineered for solvent-weld installations in horizontal or vertical pipe runs where a size transition is required.

Designed in accordance with ASTM D2665 and D3311, this bushing features a spigot end for insertion into a 2 inch hub and a socket end to receive 1-1/4 inch pipe. The configuration ensures smooth internal flow and consistent alignment with downstream components, minimizing flow resistance and turbulence in DWV assemblies.

Installation Notes

All surfaces must be dry and free of debris before priming and solvent welding. Use primer and PVC cement conforming to ASTM F656 and F493. Insert fully and hold briefly to ensure capillary seal integrity. Cure times vary by temperature and pipe diameter. This fitting is not suitable for pressurized or hot water applications.

Application Overview

Typically used in DWV systems for reducing transitions at fixture arms, branch drains, or stack connections. Common in residential and light commercial projects where code-compliant material and dimensional stability are required for gravity-fed drainage systems.

Regulatory Compliance

This product meets IPC and UPC code requirements for DWV use and is third-party certified to NSF/ANSI Standard 14 for plastic piping system components. It does not contain lead and is approved for use in building drainage systems as defined under local plumbing regulations.
