NPT (National Pipe Thread) and ORFS (O-Ring Face Seal) are both types of fittings used in fluid systems but differ in their sealing methods and applications. NPT fittings rely on a tapered thread to create a seal through thread deformation and require thread sealant for optimal leak prevention, making them suitable for lower-pressure applications. In contrast, ORFS fittings use an O-ring seated in a groove on the face of the fitting to provide a reliable, high-pressure seal, making them ideal for applications where leak prevention is critical.
