1-1/2 inch PVC DWV Adapter Plastic x Female

1-1/2 Inch PVC DWV Adapter – Socket x FNPT for Drain, Waste, and Vent Systems

The 1-1/2 inch PVC DWV Adapter (Hub x Female NPT) is a transition fitting used in non-pressurized drainage systems to connect a solvent-welded PVC pipe to a female-threaded pipe or fitting. Designed for use in residential and light commercial DWV (Drain, Waste, and Vent) systems, it provides a secure method for transitioning between piping materials or configurations.

This adapter is manufactured from Schedule 40 white PVC and conforms to industry specifications for dimensional accuracy and material performance. It is intended for use in gravity-flow drainage applications only and is not rated for pressure systems.

Performance and Application Highlights

• ✅ Connection Type: Socket (hub) x Female NPT – Designed to connect solvent-welded PVC pipe to male-threaded pipe or fittings.
• ✅ Chemical Resistance: PVC construction provides resistance to household chemicals and wastewater compounds commonly found in DWV systems.
• ✅ Corrosion-Free Material: Suitable for use in environments where metal fittings may corrode or degrade over time.
• ✅ Code Compliance: Manufactured in accordance with ASTM D2665 and meets standards for DWV applications under IPC and UPC plumbing codes.

Installation Considerations

For proper installation, clean and dry-fit all components before solvent welding. Use an ASTM-approved primer and solvent cement for the socket end, and apply PTFE tape or a compatible thread sealant to the threaded end before tightening onto a male-threaded component. Avoid overtightening to prevent stress cracks in the female hub.

Typical Uses

Commonly installed in bathroom and kitchen drainage lines, utility sink hookups, or vent transitions where a female-threaded connection is required. This adapter is appropriate for both new construction and system retrofits where alignment or component replacement is necessary.

Regulatory and Material Compliance

This fitting is lead-free and compliant with NSF standard requirements for residential and commercial non-pressurized piping systems. PVC fittings used in DWV systems do not carry potable water and are approved for use in systems operating below 140°F.
