Buying Guide: 4 Inch Schedule 80 PVC Fittings
- Material and rating: Schedule 80 PVC offers thicker walls and higher pressure ratings than Schedule 40, ideal for demanding systems. Verify compatibility with your operating temperature range and chemical exposure.
- Connection type: Socket (slip) joints require PVC cement for permanent bonds. Ensure you have the right solvent cement and primer for a reliable seal.
- Configuration needs: Elbows, tees, and wyes enable turns and branching. Choose the correct angle (45°, 90°) and the number of outlets to minimize friction losses and potential leaks.
- Size and tolerance: Confirm 4″ nominal size matches your pipe schedule and inside diameter. Schedule 80 fittings are thicker and sometimes slightly heavier; plan for handling and support.
- Chemical resistance: PVC handles many corrosive liquids, but check compatibility with solvents, oils, or acids in your system.
- Maintenance and accessibility: Union and flange fittings can ease maintenance and disassembly. Consider whether frequent disassembly is anticipated in your application.
- Standards and safety: Look for NSF or ASTM-compliant fittings for potable water or critical process lines. Always follow local code and installation best practices.
