Brass Hydraulic Fittings


JIC (Joint Industry Council) hydraulic fittings are standardized 37-degree flare fittings commonly used in high-pressure hydraulic systems for secure and leak-proof connections.

JIC fittings have a distinctive 37-degree flare design that forms a metal-to-metal seal. This differs from other fittings that may rely on elastomeric seals or different flare angles.

JIC fittings are typically made from high-grade steel, stainless steel, or brass to ensure durability, corrosion resistance, and high-pressure performance.

JIC fittings are compatible with other fittings that share the same threading and 37-degree flare standard. However, it’s important to verify thread types and dimensions before connecting.

JIC fittings are suitable for hydraulic systems in agriculture, construction, mining, and manufacturing due to their reliability in high-pressure and high-vibration environments.

JIC fittings are measured using the outside diameter of the tubing and the corresponding thread size, usually following SAE J514 or ISO 8434-2 standards.

Ensure both the fitting and tubing have clean, undamaged threads. Tighten the fitting to the manufacturer-recommended torque to create a secure, leak-proof seal.

Yes, JIC fittings can be reused as long as the threads and flare are not damaged. Proper inspection before reuse is recommended.

JIC fittings may not be ideal in highly corrosive environments or where system pressure exceeds their specified ratings.

Check for worn threads, improper tightening, or incompatible components. Replace any damaged parts, clean connections, and ensure fittings are properly torqued.
