The Allied Gomco 01-90-2878 is a replacement float assembly designed specifically for use with the 01-90-2768 metal cap. This critical safety component provides positive shut-off protection for large-capacity 2800 mL (one gallon) polycarbonate collection containers. As fluid levels rise during suctioning, the float buoyancy triggers a seal that interrupts the vacuum path, effectively protecting the pump motor from overflow and contamination. This OEM float is precision-balanced to ensure reliable activation at the correct fluid volume, maintaining the safety standards required in clinical and surgical environments.
