3 inch PVC Schedule 40 Cap

PVC Cap S40 PRES 3 inch – Solvent Weld End Cap for Schedule 40 Systems

The PVC Cap S40 PRES 3 inch is a solvent weld fitting designed for terminating the end of a 3-inch Schedule 40 PVC pipe. Commonly used in pressure, drain, waste, and vent (DWV) applications, this cap delivers a permanent seal that meets plumbing code requirements and supports long-term system integrity.

Manufactured from durable polyvinyl chloride, the cap is engineered for use in above-ground and non-pressurized below-ground systems. Its slip connection design allows for a secure bond using industry-standard primer and solvent cement.

Performance Attributes and Construction Details

Designed for professional-grade installations, this end cap is fabricated to exacting standards to ensure reliable sealing under typical operating conditions:

• ✅ Schedule 40 Wall Thickness – Complies with ASTM D1785 for pressure-rated piping components.
• ✅ Slip Socket Connection – Allows for solvent-weld installation, providing a permanent and watertight seal when bonded properly.
• ✅ Rigid PVC Composition – Offers high tensile strength and chemical resistance suitable for use in water supply, irrigation, and DWV systems.
• ✅ Corrosion-Resistant Material – Unaffected by soil conditions and common chemicals found in plumbing environments.
• ✅ Code Compliant – Manufactured to meet or exceed applicable ANSI, NSF, and ASTM specifications for PVC pressure fittings.

Installation Guidelines

For optimal performance, ensure that pipe ends are clean, square-cut, and dry-fit prior to final installation. Apply primer to both the cap socket and the pipe end, followed by solvent cement. Insert the pipe fully and hold in place to allow proper curing. Cure times should align with ambient temperature and pressure specifications outlined by cement manufacturers.

Use Cases and System Integration

Ideal for sealing off pipe ends in pressure piping or DWV configurations, this fitting is used in new construction, system testing (such as air or water pressure testing of capped lines), or during temporary shutdowns. Its compatibility with 3 inch Schedule 40 pipe makes it versatile for residential, commercial, and light industrial projects.

Technical Note

PVC fittings such as this cap offer high resistance to scaling, oxidation, and biological growth. Their use is common in applications where long-term reliability and minimal maintenance are critical.
