Low Pressure Gas Hook-Up Hoses

For engines up to 20hp, the 1/2" hook-up hose can be used "IF" the supply line "to the hose" is of sufficient size for the engine. In other words, lets say the charts show the engine requires a 1" gas line. Run 1" all the way up to the 1" shut off valve, then you can drop down to a 1/2" quick disconnect and a 1/2" hookup hose of no longer than 6 feet.

Most customers use our Quality Brass Quick Disconnect Couplers in conjunction with these rubber hook-up hoses. Get more details about the quick disconnects here: Quick Disconnect Couplers

The use of these hoses with natural gas must meet the following criteria:
*Maximum working pressure of the application not to exceed 50 psi. The application must be in an outside (non-enclosed) environment. Applications that are in an enclosed environment or greater than 50 psi working pressure are not recommended. Do not use LPG hose for fuel hose in vehicles using CNG (Compressed Natural Gas).

Observation from the Tech
Sometimes it is not an easy decision where to connect the generator to the gas system. Try to start by looking at the meter which is always best if possible. If this is not close to the power connection and if using a temporary electrical connection wire, a choice will need to be made as to which connection to favor, the gas or the electric. The gas is usually the one customers opt to run farther due to overall cost and safety. We ship a lot of custom hoses from 20', 30', 50', 70' and more. When ordering customers will usually tell us that they have called a plumbing company or their gas company and the installation cost of rigid pipe to the generator relocation would be like $400. They can order a rubber hose 70' long for $192 and take it with them if they move. No digging trenches or drilling holes in walls. For long runs like this brackets can be attached to each corner of the generator and then just wind the hose around or use a hose reel when not in use.
