High pressure screw type ISO14540 1/4 inch hydraulic quick coupler for coal mining machinery

Durable precision-engineered brass body with hardened steel locking mechanism ensures leak-free connections under extreme pressure. ISO14540 certified for seamless compatibility with global hydraulic systems.

Ultra-smooth internal sealing surface minimizes friction and wear, extending service life in high-demand mining operations. Corrosion-resistant electroplated finish withstands harsh underground environments.

Instant push-to-connect design with audible click confirmation enables single-handed operation while wearing protective gear. Safety-locked coupling prevents accidental disconnection during continuous vibration.

Optimized flow path reduces turbulence for maximum hydraulic efficiency in coal shearers, roof supports, and drilling rigs. Pressure tested to 350 bar with zero performance drop.

Exclusive triple-O-ring configuration with high-grade nitrile rubber eliminates fluid loss at connection points. CNC-machined threads guarantee perfect alignment during screw-type assembly.

Bulk purchase available with factory-direct pricing for mining equipment fleets. Compatible with all major brands of underground machinery requiring 1/4" hydraulic interfaces.
