Common types include push-to-connect, barbed, compression, and threaded fittings—each suited for different tubing and application requirements.

Selection depends on the tubing’s outer diameter (OD), the thread type (e.g., NPT, BSPT), and the pressure rating of the system. Using a fitting size chart helps ensure proper fit and performance.

Some fittings, like threaded metal ones, can be reused if undamaged, but push-to-connect fittings may wear or lose grip strength over time and should be replaced to maintain a secure seal.
