Lumax’s LX-1403 quick-release grease coupler is designed to latch firmly onto the grease fitting to create a leakproof seal for hands-free greasing with no damage to the seal. The heavy-duty LX-1403 has hardened 4-jaws engineered to withstand its working pressure of 15,000 psi and burst pressure of 22,000 psi. The integrated nonreturn valve is designed to enable the unit to be disconnected at high pressures with no spurts or splashes. The compact device is 2.9 inches long and 1.2 inches high, making it suitable for use in small, tight spaces. It has an integrated 1/8-inch NPT connection engineered to be compatible with all sizes and forms of mounts and to fit all SAE and metric grease fittings, making it suitable for use on hand, battery-powered or air-operated grease guns and bulk grease pumps. The ergonomic thumb lever design helps simplify coupling and uncoupling.
