NHRA Fireproof Brake & Fuel Line Covering Firesleeve
SAE AS1072E Firesleeve: Aviation-Marine
High Temperature, Heat & Flame & Pyro Resistant Silicone Rubber Coated Fiberglass Sleeve & Jacket: Protection for critical hydraulic, oil and fuel lines
(Allows qualified hose assemblies to pass AS1055D testing)
500°F / 260°C Continuous Exposure:
FlameShieldTM aviation / aerospace grade high temperature, heat, flame and pyro resistant firesleeve jacket is manufactured to SAE AS1072E standards so it can pass the fire testing standards of AS1055D; and the requirements of FAA TSO - C53a and TSO - C75.
It may be used for all fuel, oil, hydraulic, fire extinguisher and prop feathering lines. "Fire-proof" hose lines, as defined by the FAA, must withstand a direct flame for fifteen minutes under specified flow conditions without failure. Fire-resistant lines must withstand a 5 minute exposure under these conditions.
Fire-proof hose lines are obtained when the proper size Firesleeve is selected and properly assembled with appropriate clamps.
Firesleeve is available in sizes ranging from 0.25" Inside Diameter through 5" I.D. in 25 size steps.
Aviation / Aerospace / Marine Firesleeve
Molten metals simply slide off of the extra heavy duty coating of High-Temperature Silicone Rubber on all of these products (firesleeve), providing excellent burn-through protection.
Firesleeve pyro resistant sleeve & jacket withstands molten splash & welding splatter. Withstands 500°F / 260°C continuous exposure; 2200°F / 1205°C for periods up to 15 minutes and short flash excursions to 3000°F / 1650°C.
Firesleeve is highly flexible
To meet the installation requirements of AS1072, Firesleeve ends can be dipped in our SleeveSeal liquid silicone rubber end seal to prevent wicking of liquids and contamination.
SleeveSeal tape can be used to seal the ends of sleeve at the connector for a watertight seal. Also protects the clamp if used.
