PACIFIC, MO – Husky Corporation fuel nozzle valves for dispensing ethanol blended gasolines, diesel, and bio-diesel fuels meet enhanced Underwriters Laboratories (UL) safety standards that take effect April 30, 2015. The stringent new standards have been in the works for many years, primarily to ensure fuel nozzle valves can safely dispense enhanced ethanol and bio-diesel blended fuels.
The following Husky nozzle products were recently listed under UL 2586, the standard that now covers Flammable Liquid Hose Nozzle Valves. Product details are available at husky.com
“Husky is dedicated to continuously improving our fuel dispensing products. We are pleased these nozzle valve products passed the required test procedures to earn listing under the rigorous standards of UL 2586”, said Brad Baker, Husky Corporation Executive Vice President. “UL has been out in front of this issue and we fully support all efforts to enhance fuel dispensing safety standards.”
Customers are advised to review the UL Online Certifications Directory to verify the products they purchase meet the appropriate safety standards:

UL 2586 and Ethanol Blends
The new UL safety standards anticipate the possibility that the U.S. gasoline supply will feature concentrations of ethanol at rates higher than E 10. For example UL 2586 introduces exposure to more aggressive test fluids, requires that gaskets and seals be make of UL listed rubber materials, and calls for more demanding automatic shut-off nozzle valve endurance test requirements. Certain internal nozzle valve materials which passed safety standards under the previous applicable standard (UL 842) had to be replaced with more expensive materials to be listed under UL 2586.
New Requirement: Pressure Activation or Interlock Device on all UL Listed Nozzles
Also taking effect April 30 is a requirement that nozzles with latch-open devices must be pressure-activated or come equipped with an interlock device. This change affects applications where UL listed nozzles are required. The National Fire Protection Association (NFPA) also advocates this feature to prevent the accidental discharge of fuel from nozzles that are inadvertently stored in a latch-open position.
Fuel dispensing operations don’t need to replace existing nozzles to meet the new UL standards. However future nozzle purchases will be covered by the UL standard in place when the product was manufactured.
