CNG Vehicles Forecast
7
ProjectionsFacts about Natural Gas Vehicles
• 153,000 NGVs on the US roads
• More than 15.2 million worldwide.
• 1,564 CNG fueling stations in the U.S.,
• Refueling appliances are available for home use.
• Natural gas costs $1.50 to $2.00 less per gasoline
gallon equivalent (GGE)
• In the U.S., NGVs offset the use of about 500
million gallons of gasoline in 2014.
• NGVs meet the strictest emission standards,
including California.
• NGVs are as safe, or safer than traditional
gasoline or diesel vehicles.

Hoses for Natural Gas Dispensing SystemsANSI/CSA NGV 4.2-2014 •CSA 12.52-2014
10
Dispenser and other station hoses• Hose assemblies may be categorized by the
following classes:Class A: Hose Assembly connecting the dispenser to the fueling nozzle.
Class D: Hose assemblies used on other station equipment.
• Class “A” hoses temperature range of -40°C (-40°F)-65°C (150 F).
• Class “D” hoses temperature range of -40°C (-40°F)-85°C (185°F).
• Hose assemblies shall be electrically conductive.
• Hose cover designed to minimize fluids penetrations.
• Pressures to 5000 psi.

Flexible fuel lines, hoses and assemblies
• use as part of a vehicle on-board fuel storage
system, high pressure (Class B).
• Use as part of a vehicle low pressure fuel delivery
system, (Class C).
• Hoses shall be constructed so as to provide an
electrically conductive core.
• Hoses that have a service pressure of 2400 psi to
3600 psi.
• Engine compartment need a temperature range of
−40 °C to 120 °C (-40°F to 248°F).
• Other vehicle hoses need a temperature range of -
40 °C to 85 °C (-40°F to 185°F).
