Buying Guide
What should you consider when choosing 3/8″ push-to-connect air fittings?
- Material and durability: Plastic bodies are budget-friendly and light, but metal components offer higher impact resistance in demanding environments.
- Pressure and temperature: Ensure the fitting supports your system’s PSI and temperature range. Higher PSI and extreme temps demand sturdier designs.
- Connection type: Push-to-connect is quick, but verify tube compatibility (PU, nylon, soft PE) and thread type (NPT) to prevent leaks.
- Kit contents and flexibility: Starter kits with a mix of straight and elbow fittings simplify project planning and future expansions.
- Space and routing: Elbows help with tight routes; consider your layout to minimize bending stress on tubes.
