37° J514 Tube Fittings are precision-engineered connectors designed according to SAE J514 (JIC Standard) for reliable, leak-free performance in demanding hydraulic and fluid transfer applications. These fittings use a 37° flare sealing surface to form a strong metal-to-metal seal, ensuring maximum reliability even under high vibration, thermal stress, and pressure surges. They are widely used across industries such as hydraulics, aerospace, oil & gas, marine, and heavy equipment manufacturing.
