The SprayTech 0279446 Ball Cage is a fluid section component designed to hold and guide the inlet valve ball within compatible SprayTech sprayers such as the EP2510. This ensures proper sealing and consistent fluid intake during operation.
A worn, bent, or contaminated ball cage can prevent the inlet valve from sealing correctly, resulting in poor priming, pressure loss, or inconsistent spray performance. Replacing the ball cage restores proper fluid control and reliable pump operation.
