Hewitt Aviation Hoses
Commercial and private aviation fueling requires durable fueling hoses that work in some of the most demanding environments and temperatures while meeting stringent standards. These are the types of fueling hoses Hewitt designs and manufactures.
Hewitt 4113 Aviation Fueling Hose w/Permanent Couplings
Manufactured especially for jet fuel and higher aromatic aviation gasolines used in commercial and private aircraft. It is available in eight diameters (.75 to 4 inches) and is recommended for all types of riser deck, reel, and hydrant hose applications. All Hewitt aviation hose assemblies receive a unique serial number, are 100 hydrostatic tested to 600 PSI, inspected for electrical continuity, and come with a test certificate.
