1-1/4" Schedule 80 PVC Pipe Plain End - 1-5ft

This premium-grade 1-1/4-inch Schedule 80 PVC Pipe is made from high-strength polyvinyl chloride that’s built to last. Its thicker wall design makes it significantly more durable than Schedule 40 alternatives, providing superior resistance to corrosion, abrasion, and chemical exposure.

When comparing PVC schedule classifications, Schedule 80 offers enhanced performance and pressure resistance, making it a preferred choice for demanding environments. Perfect for pressure-heavy systems, the pipe’s plain ends allow for simplified coupling with solvent-welded or threaded fittings, offering greater versatility during installation.

Benefits of Schedule 80 over Schedule 40:

• Thicker walls for greater strength and impact resistance.
• Suitable for high-pressure and industrial applications.
• Superior long-term performance in corrosive environments.

Installation & Handling Tips

Ensure safe, code-compliant installation by following these best practices:

• Use solvent cement and primer approved for Schedule 80 PVC.
• Space supports properly to prevent sagging (follow local code).
• Install expansion loops for thermal movement in long runs.
• Avoid direct sunlight exposure—paint with reflective white paint if outdoors.
• Store pipe on flat surfaces to prevent bowing.
• Never exceed 140°F or 400 PSI working limits.
• Always verify compatibility with fittings (e.g., ASTM D2464) and flanges. 

Installer Tip: For threaded applications, use only compatible fittings and apply thread sealant rated for PVC systems. Confirm code compliance before installation.
