2-1/2 inch PVC Schedule 40 Coupling Plastic x Plastic

2-1/2” PVC Schedule 40 Coupling – Socket x Socket for Solvent-Weld Systems

The 2-1/2” PVC S40 Coupling is engineered for solvent-weld applications in pressure and non-pressure piping systems. Manufactured from rigid polyvinyl chloride (PVC), this coupling provides a durable, corrosion-resistant solution for joining two segments of Schedule 40 PVC pipe. The socket ends are designed for use with primer and solvent cement to form permanent, watertight connections.

Commonly used in potable water systems, irrigation, and industrial piping networks, this fitting delivers consistent performance in both above-ground and underground applications. It meets ASTM and NSF standards and is suitable for systems requiring compliance with plumbing or mechanical codes.

Key Performance Features

• ✅ Material: Rigid white PVC with smooth internal bore for optimal flow characteristics
• ✅ Connection Type: Socket x Socket (Slip fit for solvent cement bonding)
• ✅ Pressure Rating: Suitable for use in pressure-rated Schedule 40 systems up to 150 psi (at 73°F)
• ✅ Corrosion Resistance: Inert to most acids, alkalis, salts, and organic solvents
• ✅ Temperature Range: Up to 140°F (60°C) depending on pressure and application

Specifications

• Nominal Size: 2-1/2 inches
• Standards: ASTM D2466, NSF 14 & NSF 61 certified
• Application: Potable water distribution, DWV (drain-waste-vent), irrigation, industrial fluid handling

Installation Notes

Use of a compatible primer and solvent cement is required for proper installation. Clean and dry all surfaces prior to bonding. Insert pipe fully into socket until bottomed out, and hold for a few seconds to ensure joint integrity during the cure process. Allow adequate cure time based on temperature and pipe diameter before pressure testing.

Common Use Cases

This Schedule 40 PVC coupling is widely specified in municipal, commercial, and residential systems. It is typically used to extend or repair straight runs in pressure water lines or to adapt pipe segments within venting systems, irrigation laterals, and filtration assemblies.

Did You Know?

PVC Schedule 40 pipe and fittings are favored for their high tensile strength-to-weight ratio, chemical stability, and long-term performance in buried and exposed installations.

The 2-1/2” PVC Coupling delivers proven durability and reliable sealing performance in a variety of fluid-handling environments. Designed to meet industry codes and jobsite demands, it is a staple component in professional-grade plumbing installations.
