What types of pneumatic fittings are available?

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

How do I choose the right size pneumatic fitting?

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.

Can pneumatic fittings be reused?

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.
