QUESTIONS & ANSWERS
Kevlar® provides lightweight strength, flame resistance, and abrasion protection, making it far superior to traditional fabric or rubber covers. The KPC3-775-625’s single-layer Kevlar® construction prevents scratching while resisting environmental hazards like heat, chemicals, and UV exposure. This ensures long-lasting protection for sensitive pitot probes.
This pitot probe cover prevents foreign object damage, contamination, and weather exposure, all of which can compromise probe accuracy. Its NAS1756-approved warning streamer acts as a clear “Remove Before Flight” reminder, helping ground crews avoid leaving covers installed during takeoff. By protecting vital sensors, the KPC3-775-625 reduces the risk of costly delays and safety hazards.
Each KPC3-775-625 pitot probe cover is factory-tested for pull-off resistance, ensuring it remains securely in place during ramp operations. The tight fit prevents accidental detachment from wind, vibration, or movement, while still allowing for easy removal with the integrated loops. This balance of security and accessibility streamlines ground handling.
The KPC3-775-625 is metal-free and low-particulate, eliminating the risk of scratching delicate probe surfaces or introducing conductive contaminants. This design choice ensures compatibility with strict aerospace safety requirements. It also makes the cover lightweight and easier for technicians to handle.
The cover is manufactured under ISO 9001 and AS9100D quality standards, ensuring rigorous aerospace-grade production. It complies with CFR 25.853 flammability requirements, meaning it won’t melt or ignite under tested conditions. These certifications confirm its reliability and compliance for use on commercial and military aircraft.
The NAS1756-approved warning streamer on the KPC3-775-625 provides a clear and standardized “Remove Before Flight” signal. Its bright color and durable construction make it highly visible during preflight checks. This feature minimizes the chance of accidental takeoff with covers in place, protecting both safety and operational efficiency.
Yes, the cover is built with chemical- and abrasion-resistant materials, ensuring protection against deicing fluids, hydraulic fluids, jet fuel mist, and other contaminants found on the ramp. This resistance extends the cover’s service life and maintains the integrity of pitot probes in demanding maintenance environments.
The pitot probe cover includes built-in installation and removal loops, allowing ground crews to fit or remove it quickly without tools. For added convenience, it can also be used with a removable pole for higher or harder-to-reach probe placements. This makes it an efficient choice for busy airline and MRO operations.
The KPC3-775-625 includes a water-repellent lamina that prevents moisture from seeping into the probe during rain, snow, or washdowns. Water inside a pitot probe can freeze at altitude, leading to inaccurate readings or system malfunctions. By repelling water, this cover helps maintain flight safety and probe accuracy.
