Parts of JIC include which components?

• A. Nut, bolt, gasket
• B. Fittings, flare nut, sleeve
• C. O-ring, clamp, sleeve
• D. Threaded pipe, sealant

Answer: (B)

JIC fittings seal with a 37-degree flare, forming a metal-to-metal connection. The parts that make up a typical JIC connection are the fitting body (the male or female part that creates the connection), the flare nut (the threaded nut that tightens the flare onto the seat), and the sleeve (the tube end accessory that supports and shapes the tubing as it forms the flare). When the flare is formed on the tube and the flare nut is tightened, the flare mates against the seating surface inside the fitting to create the seal. The other options don’t fit because a bolt and gasket aren’t used in JIC flare assemblies; an O-ring and clamp are more typical of different connector styles; and threaded pipe with sealant refers to pipe-thread joints, not SAE JIC flare fittings.
