When shopping for a fitting kit for your air system, there are a few essential factors to consider to ensure a proper fit and reliable performance. First and foremost, you need to confirm the fitting sizes match your system’s tubing and threaded ports. Check for both the outer diameter (OD) of your air lines and the NPT thread size of your compressor, air tank, or valves. The best kits clearly label the dimensions of each fitting and often include a variety of sizes to accommodate different setups.
Next, consider the material. Brass is widely regarded as the top choice for air systems due to its superior strength, resistance to corrosion, and ability to withstand high pressure. Brass fittings also thread more smoothly and create more reliable seals compared to plastic or steel alternatives.
Variety and convenience also play a role. A well-stocked kit should include straight fittings, elbow connectors, tee fittings, and bulkheads. This ensures you have the flexibility to route your air lines neatly and securely—even in tight or complex spaces. Look for kits that come with push-to-connect fittings if you want an easy, tool-free installation process.
Durability and pressure ratings are also important. Make sure the fittings are rated for the maximum PSI your system operates at. Using under-rated fittings can lead to leaks or catastrophic failure.
