NPT vs. G Thread: Choosing Fittings for Airtac 4V210-08

NPT or G Thread? Getting the Right Fit for 4V210-08

One of the most common installation errors for the Airtac 4V210-08 is choosing the wrong thread type. This leads to leaks and damaged valve bodies.

Understanding the Difference

• G Thread (BSP/Parallel): Common in Europe and Asia. Requires a sealing washer or O-ring.
• NPT (Tapered): Standard in North America. Relies on thread interference and Teflon tape for sealing.

Warning: Never force an NPT fitting into a G-thread valve. Always check the model suffix on your Airtac box to ensure compatibility with your local plumbing standards.
