The Groz HC/14/4/B 4 Jaw Professional Hydraulic Grease Gun Coupler is a heavy-duty hydraulic grease coupler designed to provide a secure connection between a grease gun and the grease nipple during lubrication operations. Its 4-jaw gripping mechanism is designed to firmly engage compatible grease fittings and help maintain a reliable connection while grease is being delivered under pressure.

The professional hydraulic coupler is particularly useful for workshop servicing, automotive maintenance, agricultural machinery, construction equipment and industrial lubrication. Its robust construction is intended for repeated use in demanding maintenance environments.

The 4-jaw design provides strong engagement with the grease nipple, helping reduce accidental disconnection during pumping. This makes it useful when lubricating components that require consistent pressure to force grease into bearings, bushes, pins, joints and other lubrication points.

Wide Application Details

The Groz HC/14/4/B is suitable for automotive workshops, tractors, agricultural machinery, excavators, loaders, construction equipment, industrial machinery, heavy vehicles and general mechanical maintenance. It is especially useful for professional technicians who require a reliable hydraulic connection between a grease gun and standard grease fittings.
