Buying Guide
What to consider when choosing 4-way 1″ PVC fittings:
- Material grade: Furniture-grade PVC offers greater rigidity and a cleaner look, suitable for visible indoor projects and outdoor furniture with protection.
- Pressure rating: Look for fittings rated for at least 300 PSI for furniture structures and 450 PSI when indicating higher flow or load demands inside walls.
- UV resistance: UV-stabilized fittings prevent yellowing and cracking when used outdoors or in sunlit spaces.
- Finish and aesthetics: A smooth interior surface reduces friction and supports smoother fluid dynamics for any planned water or air flow in rare cases.
- Pipe compatibility: Confirm outside diameter compatibility (typically 1.315″ for 1″ Schedule 40 pipes) to ensure a snug, leak-free fit.
- Quantity and variety: For larger projects, buying in packs (10–12 pieces) can provide consistency and reduce mismatches across the build.
- Indoor vs outdoor use: Choose products explicitly rated for UV exposure and temperature ranges appropriate to your climate.
