5 FUEL TYPES Parker Gold Label Aircraft Fueling Hose is designed and manufactured for use with most common aviation fuels such as Jet A, Jet A1, JP5, JP8 and 100LL Avgas (see chart), incorporating a premium grade nitrile tube specifically formulated to handle the high aromatic content of aviation fuel, with minimal permeation. • Aviation gasoline (avgas) – a high octane/low flash point fuel specially formulated to maintain its liquid phase (rather than vaporizing) at high altitude. The low flash point provides lower ignition properties, and the liquid phase of the fuel prevents vapor lock in the onboard fuel delivery system. It is typically used to power small private or commercial aircraft that incorporate piston engines. Avgas is available in two primary grades: Standard avgas (leaded gasoline) and LL avgas (low-lead gasoline); these fuels are often dyed to identify them for proper use. • Jet Propellant (JP)– primarily a kerosene-based jet fuel specially formulated for larger commercial, private or military aircraft incorporating gas-turbine engines. The high flash point provides safer storage and transportation properties. Jet fuel is available in a variety of formulations, and is typically clear or straw-colored.

Unless properly drained/grounded, this charge could build and create a spark that ignites fuel or fuel fumes. All Parker Gold Label Aircraft Fueling Hose is manufactured with static conductive rubber compounds and/or a dual wire helix suitable for conducting an electrical charge to ground. Factory-fabricated hose assemblies are also tested for hydrostatic pressure and electrical conductivity. Spillage Control Aviation fuel is extremely flammable. Fuel spillage creates the risk of environmental harm and fire or explosion, leading to property damage, personal injury or death. A dispensing system equipped with a deadman control incorporates a hand-held electric, hydraulic or pneumatic handle/switch that is connected to a cable or hose reel assembly and then to a fuel flow control valve. The deadman control prevents fuel from flowing until the handle/switch is engaged; when the handle/switch is released, the fuel flow stops. To minimize accidental spillage, Parker offers Deadman and Twin Sensing hoses in industry-standard sizes, lengths and color combinations for reliable service in this application.
