Lumax Quick Release Grease Coupler, 15,000PSI

Lumax Quick Release Grease Coupler, 15,000PSI

The LX-1403 Lumax Quick Release Grease Coupler is a high-pressure, lock-on grease coupler built to make greasing faster, cleaner, and a whole lot less like an arm-wrestling match with a zerk. Its proprietary locking and quick-release mechanism creates a leak-proof seal and firmly latches onto the grease fitting for true hands-free greasing. If a fitting is pressurized, just depress the thumb lever to release—no broken fittings, no sudden grease fireworks, and no new abstract art on your shop wall.
