NPT (National Pipe Thread) fittings are tapered thread fittings that create a seal by wedging the threads together, often requiring thread sealant. ORB (O-Ring Boss) fittings, on the other hand, use straight threads and an O-ring to create a seal, providing a more reliable and leak-free connection in high-pressure applications.
