40 Feet 1/2 inch ID Natural Gas Hose
Best for Backyard Distance
Now we’re talking serious distance. If your gas stub is on the deck but you want the noisy generator behind the shed, you need this 40-footer. Despite the length, the 1/2-inch ID (Inner Diameter) is crucial here. It maintains pressure so your generator doesn’t starve and stall under load. Perfect for large properties.
Key Features:

- Standard QD: Comes with a 1/2″ quick disconnect kit for the supply side.

48FT Natural Gas Hose for Generator
Best for Maximum Reach
This is the big kahuna. 48 feet of line allows you to put your generator practically in the neighbor’s yard (don’t actually do that). It’s designed specifically for generators that need a long leash. It comes with a specific 1/2″ Male Flare to 3/8″ Female Flare adapter, covering the most common connection types found on portable gensets.
Key Features:
- Massive Range: nearly 50 feet of freedom.
- Adapter Bonus: Includes flare adapters often missing in other kits.
- CSA Certified: Safety tested for outdoor weather and gas integrity.
Pros & Cons
- Pros:
- Ultimate flexibility in positioning.
- Includes versatile flare adapters.
- Thick wall construction resists kinks.
- Cons:
- Verify BTU drop; some smaller meters might struggle at this distance.
If you have a complex yard or need extreme distance for safety, this is the only hose that reaches. Buy it if you need the length, skip it if you don’t.
Quick Buying Tip
Don’t ignore the “ID” (Inner Diameter). Always buy a hose with a 1/2-inch ID for generators; standard 3/8-inch grill hoses often restrict gas flow too much, causing your generator to surge or stall when you turn on the AC.
