Buying Guide

Metal fittings are the backbone of any plumbing or framing job. Pick the right ones and your work stays solid.

When you open a fitting box, you feel that satisfying click. The parts fit together like a puzzle; no sweat, no fuss.

  • Material: Choose brass, steel, or cast iron. Brass stays strong and rust‑free. Steel is cheap but can rust if not treated. Cast iron works for heavy duty.

  • Size & Thread: Check the diameter and thread count. Make sure it matches your pipe. Small mistakes mean leaks.

  • Compatibility: Look for DOT or SAE if you use trucks or air brakes. Standard pipes use NPT or PVC.

  • Connection type: Quick‑connects are fast. Threaded ones stay tighter for long term.

  • Temperature range: Think cold or hot. Some fittings only work up to 120 °F. Those for engines go up to 300 °F.

  • Pressure rating: My car air brakes need higher pressure. Verify the PSI rating on the label.

  • Durability: Zinc die‑cast or heavy‑forge is more durable. Plastic is cheap but not long‑lasting.

  • Finish: Black paint holds rust; chrome looks shiny. Choose what fits your décor.

  • Warranty: A 1‑to‑3‑year warranty keeps you safe.

  • Price vs quality: Cheap sometimes saves money. But cheap can break sooner, costing more later.

  • Accessories included: Bundles that have elbows, tees, and caps save time.

  • Safety: Look for certifications. They prove it meets industry standards.

  • Installation tools: Some fittings need wrenches. Others snap on. Pick the kind you already have.

  • Noise: Some fittings create hissing sounds. Test a small batch if noise matters.

  • Weight: For mobile projects, lighter is better.

When you finally install your fittings, you will feel proud. The pipe works smoothly and lasts years.
