2C81801G01 is a precision aerospace component, compliant with AS9100D quality standards and FAA/EASA regulations, designed for the environmental control systems (ECS) of large commercial aircraft.

It acts as an ECS air duct connection seal, forming a tight, pressure-stable seal between segmented ECS air ducts. This seal prevents conditioned air leakage during the transmission process, ensuring that the volume and temperature of air supplied to the cabin, cockpit, and avionics compartments meet the required standards, avoiding uneven cabin temperature, insufficient avionics cooling, or increased ECS energy consumption during flight.

Made from flexible, heat-resistant EPDM rubber with reinforced fiber layers, it operates stably at -55°C to 200°C, and resists abrasion and aging. Weighing 0.09kg, it enables fast MRO installation and replacement, a critical component for ECS operation efficiency.
