Frequently Asked Questions

AI
NPT (National Pipe Taper) threads are tapered to create a tight seal when tightened. Unlike straight threads, they rely on thread deformation for sealing, making them standard for North American plumbing and pneumatic systems.
Stainless steel and brass are the best choices for wet or outdoor environments due to their high corrosion resistance. Chrome-plated steel is suitable for dry indoor air tools but may rust if exposed to moisture over time.
Yes, using thread sealant tape (Teflon tape) or pipe dope is recommended for NPT fittings. It ensures a proper seal and prevents leaks, especially in high-pressure air or gas applications.
