Overview
The 123-17364-405 is a premium, high-visibility Flame-Retardant Pitot Tube Cover custom-engineered for the exterior air data sensor protection of Boeing 737 and Boeing 757 commercial aircraft fleets. Classified as a critical airframe Ground Support Equipment (GSE) ramp safety asset, this specialized hardware is purpose-built to encapsulate and shield the delicate pitot probes from environmental contaminants, moisture ingress, insect nesting, and incidental ramp impacts during ground storage or hangar maintenance intervals. Manufactured by JUNXUN to meet strict aerospace fire-safety specifications and environmental tolerance indices, the 123-17364-405 ensures an absolute, heavy-duty protective barrier that isolates the internal pneumatic orifices of the probe without causing thermal melting or leaving chemical residues on the high-value sensor plating.

Key Points
Engineered Boeing Fleet Fitment: Custom-contoured to slide smoothly and snugly over the specific geometric profiles and aerodynamic swept angles of standardized Boeing 737 and 757 pitot static probes.

Advanced Flame-Retardant Fabric: Fabricated from high-grade, self-extinguishing aerospace textiles engineered to withstand high ambient ramp temperatures and accidental contact with residual pitot heater cycles.

High-Visibility Safety Warning: Outfitted with an ultra-durable, weather-resistant "Remove Before Flight" warning streamer to ensure instant recognition by flight crews and line maintenance inspectors prior to dispatch.

Weatherproof Contamination Seal: Designed with an internal non-abrasive lining and a secure mechanical closure mechanism to completely prevent wind-blown dust, rain erosion, and de-icing fluids from entering the pressure ports.

Applications
Aircraft Overnight Hangar Storage: Deployed by line maintenance crews as a mandatory safety fixture during overnight parking or extended remote ramp storage to preserve air data system operational readiness.

Airframe Wash and Exterior MRO: Utilized during scheduled C-checks, airplane painting, or fuselage washing sequences to prevent high-pressure water, chemical soaps, and debris from clogging critical pressure lines.

Fleet Hangar Ground Maintenance: Essential tool crib inventory for international commercial airlines and third-party MRO facilities servicing single-aisle and twin-aisle Boeing fleets to maintain mandatory safety protocols.
