The Allied Gomco 01-90-2394 is a critical replacement gasket designed to maintain an airtight seal between the collection bottle and the metal cap assembly. Specifically engineered for use with the 01-90-2768 cap and float assembly, this gasket ensures the vacuum pressure remains consistent during clinical suction. It is a vital component for 1200 mL polycarbonate or glass collection bottles, preventing leaks and protecting the pump motor from potential fluid overflow.
