4 inch PVC DWV Adapter Plastic x Female

4 inch PVC Schedule 40 Female Adapter – Socket x FIPT Connection for DWV and Pressure Systems

The 4 inch PVC Female Adapter is a solvent-weld fitting used to transition from solvent socket connections to a female-threaded connection. This fitting features a socket (hub) inlet and a female NPT outlet, allowing secure transition from PVC piping to male-threaded metal or plastic components in both drainage and pressure-rated systems.

Manufactured from rigid polyvinyl chloride (PVC), this adapter meets dimensional and performance standards applicable to Schedule 40 fittings, providing a corrosion-resistant, watertight joint for indoor and outdoor piping systems.

Product Features

• ✅ Socket x FIPT Configuration – Facilitates solvent weld on one end and threaded pipe or fitting on the other, enabling dissimilar connection methods in a single fitting.
• ✅ Schedule 40 Wall Thickness – Rated for both pressure and non-pressure applications within the limits of ASTM D2466.
• ✅ Chemical Resistance – PVC material resists degradation from common household and industrial chemicals, making it suitable for diverse applications.
• ✅ Code Compliance – Conforms to ASTM and NSF requirements for use in potable water and DWV systems when certified accordingly.

Specifications

• Nominal Size: 4 inches
• Material: PVC (Polyvinyl Chloride), Schedule 40
• End Types: Hub (socket) x FIPT (female iron pipe thread)
• Standard Compliance: ASTM D2466; NSF 14 and 61 listings where applicable

Installation Guidelines

Solvent-weld the socket end using approved primer and cement following standard cure times based on ambient conditions. Apply thread sealant or PTFE tape to the male-threaded mating component to prevent leaks at the FIPT end. Do not overtighten, as excessive torque can damage the threads or compromise sealing performance.

Applications

This female adapter is used in drainage, waste, and vent (DWV) systems, as well as in low- to moderate-pressure cold water distribution. Common use cases include pump connections, irrigation valve integration, system cleanouts, and transitions to threaded service lines.

System Compatibility and Safety

Ensure compatibility with both pipe size and application pressure ratings. For potable water use, fittings must bear appropriate NSF certification markings. Threaded connections should be installed in accordance with applicable local codes and manufacturer torque specifications.

The 4 inch PVC Female Adapter offers a reliable interface between solvent-weld and threaded components, supporting code-compliant construction across commercial, residential, and light industrial systems.
