Aircraft fueling with avgas and jet fuel in cold temperature environments

GOLD LABEL® Cold Temperature Aircraft Fueling Hose EI 1529, NFPA 407

Series 7776CT is a low temperature, high pressure hose for top deck reel and platform type aircraft fueling equipment. The proprietary rubber compounds enable this hose to stay flexible in extreme low temperatures, and the hose construction and materials provide a path to conduct a static electrical charge to ground. The premium nitrile tube minimizes permeation and will not contaminate product going through the hose, and the nitrile cover is resistant to abrasion, oil and weathering. The hose is also suitable for defueling service at low pressures (suction/vacuum rating to 8 in. Hg).

NOTES:
• Refer to Technical Resources>Critical Applications for safety, handling and use information.
• Refer to Technical Resources>Guides & Tables for fuel compatibility and service conditions.
