The Cat Pumps 45618 is a genuine OEM brass male adapter for Cat Model 56, 57, and 60 plunger pumps. In Cat pumps, the male adapter is typically part of the packing (seal) stack. It sits against the V-packings and supports them, giving the seals a solid, correctly shaped surface to press against so they seal evenly around the plunger. When an adapter wears, scores, or deforms, the packings can’t seat properly. The result is water leaking from the pump head, pressure loss, and short seal life. Installing a fresh adapter during a packing rebuild gives the new seals a proper foundation and helps the repair last. Brass construction resists corrosion and wears well in this high-pressure, water-wetted location.
