The Groz Grease Coupler with machined jaws is designed for high-pressure greasing applications. Precision-machined jaws ensure a secure and leak-proof connection to the grease fittings. Jaws are machined from high-tensile steel and assembled as a single unit. On usage, jaws break away from a single unit into 4 pieces making a perfect fit on grease nipple. The fully heat-treated coupler body and jaws withstand high pressures upto 6000 PSI without any deformation making it a perfect coupler for high-pressure greasing applications.

Amongst the most popular couplers, these are ideal for use with all hand-operated Grease Guns.
