Of the hydraulic tubing fittings illustrated, the flared fitting for high pressure use is represented by figure __________. GS-0100

Correct Answer: Option B — A or B

Flare-type fittings rely on the mechanical compression of a flared tube end against a matching seat. Figures A and B represent standard 37-degree JIC or 45-degree SAE flare connections, which are the industry standard for high-pressure hydraulic applications to ensure a metal-to-metal seal against fluid leakage.
