Buying Guide: Key Considerations For 1 Inch PVC Fittings
- Pipe compatibility: Most 1″ fittings fit 1.315″ outer diameter SCH40 pipes. Verify pipe OD before purchasing to ensure a snug fit.
- Material grade: Furniture-grade fittings are designed for stronger joints and a cleaner look. Choose if you’re building visible furniture or weight-bearing frames.
- Connection method: Many fittings require primer and solvent cement for a secure seal. Plan for ventilation and cure time when joining pipes.
- Usage environment: UV resistance and corrosion tolerance matter for outdoor projects. Indoor-only builds may benefit from aesthetics and finish.
- Project scale: Bulk packs are convenient for larger builds, while small packs fit quick repairs or singular projects.
- Limitations: Some sets have limited piece counts or focus on specific angles. Consider whether you need elbows, tees, or couplings in a single package.
- Availability and replacements: If you anticipate future repairs, consider kits that include extra fittings or a compatible brand family.
