Fire Protection

Aircraft hose assemblies located partially or totally in "Fire Zones" must have fire protection. "Fire Zone" is the area of the engine compartment forward of the firewall.

 The FAA recognizes two types of fire protection in regards to aircraft hose assemblies, fire resistant, and fire proof. In all cases fire protection is provided using two methods: 1. Silicone covered fiberglass (Firesleeve , p/n 2650-size)

 Firesleeve installation tips Firesleeve should be cut slightly longer than desired as the Firesleeve shortens slightly when you push the hose through and the Firesleeve expands. Also, if the hose has a bend it will be necessary to cut the Firesleeve slightly longer to make up for the extra length required on the bend.

 Coat Firesleeve ends with red RTV to prevent liquid wicking up sleeve.
