Product Overview

The CAT Ceramic Piston 11 x 41 (280/290) is a genuine OEM replacement piston for CAT plunger pumps. Ceramic pistons are essential for maintaining smooth pump operation, long service life, and resistance to wear and heat. Over time, pistons may crack or wear down, resulting in pressure loss, reduced efficiency, or pump failure. Replacing them with genuine CAT parts guarantees reliable performance and extended pump life.

Each piston is sold individually.
