Which component corresponds to a button head, flush type fitting, hydraulic zerk?

• A. Grease gun fitting
• B. Blasting, Propel Dry Abrasive, Blast Cabinet
• C. Water displacement thing
• D. Corrosion removal tool

Answer: (A)

The key idea is recognizing lubrication fittings used to attach a grease gun. A grease gun fitting (a zerk) comes in low-profile forms like button-head or flush-mount designs, and there are hydraulic zerk variants designed for delivering grease under higher pressure. These fittings are the interface you connect your grease gun to in order to lubricate bearings, joints, or other fittings. The other items listed relate to cleaning or surface treatment, not lubrication fittings, so they don’t match the described components.
