← All refill stations in San Antonio–New Braunfels, TX
Before you drive
Guadalupe Gas Co. is listed on our San Antonio–New Braunfels, TX propane refill guide under New Braunfels. This page is the station detail view: call and maps first, then the published facts we captured from the public source page. We do not invent hours, phones, or prices — if a field was unknown on the source, it stays unknown here.
Refill vs exchange: a refill puts propane into the tank you own (billed by gallon or weight). An exchange cage swaps tanks for a flat fee and is usually limited to 20-lb grill cylinders. If a Maps pin is only a locked cage with a card reader and no fill equipment, you are in exchange territory.
What to bring: the empty (or low) cylinder you own; a readable collar with manufacture/requalification dates; an OPD valve on cylinders through 40 lb propane capacity; and a tank free of heavy rust, dents, bulges, or a damaged foot ring/collar. Out-of-date or damaged tanks are commonly refused. Legal fill leaves vapor space (~80%); expect a partial “full,” not a brick-solid cylinder.
Gallon prices and live attendant coverage change — omitted on purpose. Use Call first, then Maps. Spot a closed yard or wrong hours? Report closed / wrong hours.
