Product Overview

The CAT Ceramic Piston 20 x 77 (650) is a genuine OEM replacement piston for CAT plunger pumps. Ceramic pistons are a critical wear part that provide exceptional durability, smooth pump operation, and resistance to high temperatures and abrasion. Over time, pistons can wear or crack, leading to reduced pressure, efficiency loss, or pump damage. Replacing them with genuine CAT pistons ensures long-lasting reliability and performance.

Each unit is sold as one piston.
