Review on 💧 Silver Heavy-Duty Quick Release Grease Coupler - Lumax LX-1403, 1/8" NPT, 1 Pack. Integrated Non-Return Valve for Easy Disconnection at 15,000 PSI Pressure. by Gary Revils

In the first picture the clutch has been installed on my new Dewalt 20v grease gun. Before the coupler even saw the Zerk fitting, the metal fitting connecting the coupler to the grease gun hose had snapped and grease was leaking out of the crack. The grease that comes out is the "test" grease that Dewalt uses. I tried to remove this grease from the system into the trash can. I tightened the clutch fitting to the same depth as the Dewalt clutch. I'm 160 pounds soaking wet so putting them on is no problem. Now look at the second photo I took and you will understand why this clutch failed so easily. In the photo, a competitor's fitting is next to a Lumax fitting. For a 15,000 psi clutch, this Lumax fitting is awfully thin. I contacted Lumax regarding this issue and received no response within 48 hours. My conclusion: pay the extra money for a quality tool. This tool is not very good quality.
