These custom-made pitot covers work great on the Cessna 525 series aircraft.  Made of aramid-fiber reinforced high temperature silicone with high visibility reflective flags. The covers provide excellent protection from the elements and pesky insects that want to build nests in your pitot probes. While they utilize high-temperature tolerant components (in excess of 350F) they aren't designed to be left on when heat is applied to the probes, or installed when the probes are hot.  However, in the unlikely event the probes are energized with the probes on, you have much higher resistance to melting or damage to your probes. This same Personal Wings design has been used on hundreds of jet probes since 2018  with excellent results. Choose the 2 or 3 Pitot Probe Cover set, depending upon your Citation.
