The Allied Gomco 01-90-2139 is a conductive rubber cap designed specifically for use as a patient-side port cover on Gomco glass collection bottles. Manufactured from high-quality conductive rubber, this cap helps dissipate static electricity, which is a vital safety requirement for equipment used in surgical suites where flammable anesthetic gases may be present. This component ensures an airtight seal at the patient tubing connection point, maintaining the necessary vacuum pressure for effective clinical suction. Its durable rubber construction resists wear from standard cleaning and sterilization protocols, making it a reliable choice for long-term use in hospital and surgical settings.
