LKJI SUPER HIGH PRESSURE QUICK COUPLING is engineered for ultra-high-pressure (70MPa) hydraulic systems requiring reliable, leak-proof connections. Designed with an external thread locking structure (M16×1.5, NPT3/8), it ensures secure self-sealing during rapid disassembly or maintenance. Crafted from corrosion-resistant brass or high-strength carbon steel, it combines metal hard seals with rubber auxiliary rings for dual leak prevention. Ideal for hydraulic jacks, ultra-high-pressure pumps, and mold equipment, this coupling supports metric, NPT, and BSP threads, ensuring seamless compatibility with Parker, FASTER, and AEROQUIP equivalents. Optimize system efficiency and safety in industrial settings with this versatile, heavy-duty connector built for extreme pressure endurance.
