. The coupler is designed to be used with all standard grease guns, including the Metric Zerk and SAE ones. It has a built-in pressure relief valve which allows it to release easily even at extreme pressures. The seal can be replaced by replacing the original one. Not recommended for use with hydraulic systems.
Utool 360 Swivel Handle provides trouble-free operation. The handle is made of heavy duty steel and has a corrosion-resistant coating, providing longer life and stable performance. It can also be used as a stand-alone device to prevent damage to the gasket. The coupler comes with a lifetime warranty against defects in materials and workmanship. Notably, Utool does not sell any spare parts.
