Quick-release locking design with double handles: securely locks onto grease fittings and lets you attach or remove the coupler rapidly. Reduces effort and speeds routine lubrication so jobs get done faster and with less fumbling. Leak-proof performance: internal seal and reinforced nozzle prevent grease from leaking under pressure. That keeps fittings, tools, and work areas cleaner and reduces wasted lubricant. High-pressure capability: rated to 10,000 PSI, compatible with most grease guns and built for heavy-duty automotive, agricultural, and mechanical maintenance tasks. Durable, precise construction: made from high-strength steel with a -resistant finish for long service life. The precise coupling delivers grease reliably to hard-to-reach or stubborn fittings. Compatibility and function: works with standard grease gun setups and common grease fitting types; designed for fast attachment, secure locking, and consistent flow under pressure. Typical applications Fleet and automotive maintenance: quickly service chassis points, U-joints, and steering components during routine vehicle inspections. Agricultural and heavy equipment: access remote grease fittings on tractors, combines, and construction machines without excess spillage. Industrial and shop use: maintain bearings, pivots, and other mechanical linkages where a secure, high-pressure coupling and precise grease delivery are required.
