JIS (Japanese Industrial Standard) hydraulic fittings are hydraulic fittings commonly used in Japan and other parts of Asia, which connect hydraulic hoses and tubes in machines used in factories, construction sites, and farms. JIS fittings are known for their BSP thread with 30-degree flare angle for male fittings and 30 degree seat for female swivel fittings. This angle helps create a strong seal between the fitting and the hose or tube, preventing leaks when under pressure. JIS fittings come in many sizes, from small ones for low-pressure systems to larger ones for high-pressure use.

QC Hydraulics manufactures stainless steel JIS Hydraulic Fittings known for their corrosion resistance and durability. These high-quality, precision fittings are ideal for industries requiring reliable, long-lasting hydraulic components.
