Lumax equipped their Locking Grease Coupler with their proprietary lock and release mechanism. This innovative design enables you to latch firmly onto grease fittings. A hardened 4-jaw design and an integrated non-return valve allow this coupler to withstand high pressures. This compact, heavy-duty coupler features an integrated 1/8-inch NPT connection. This connection makes it compatible with most hand, battery-powered, or air-operated grease guns. Never worry about broken fittings again with Lumax's Locking Grease Coupler. Using this coupler also results in less mess and less wasted grease. Its compact size enables you to reach into small, tight spaces. The Lumax Locking Grease Coupler offers you the worlds highest pressure rating! The integrated non-return valve makes the unit easy to disconnect at up to 15,000 psi. It also allows the tool to withstand up to 22,000 psi burst pressure. The hardened design prevents deformation at these high-pressure ranges. Moreover, thanks to the high-performance hydraulic seal, this coupler gives you years of use. This coupler pairs perfectly with any of our Lumax grease guns.
