• NPSM fittings include an inverted 60 deg cone inside an internally threaded swivel union nut
• Male NPTF fittings that have a 30 deg internal chamfer that make a 60 deg inverted cone, will mate with NPSM swivel unions
• The mating male threads must include an inside chamfer on the end of the fitting that mates with the inverted cone
• Threads are for clamping force only
• The sealing occurs on a small radial section between the male fitting internal chamfer and the swivel union inverted cone
• NPT and NPTF pipe threads seal by wedging the tapered threads through deformation into each other
• Both of these threads require thread sealants to complete a seal
