We Have What You Need!

Eureka Oxygen is your one-stop-shop for cannabis extraction supplies, welding equipment, and expert guidance. Small task or big project? It doesn’t matter; we have what you need.

For Welding

There was a time not that long ago when industrial gas meant simply acetylene and oxygen for welding. Now we carry a wide selection of industrial gases and mixes to fit the needs of our varied customers. Whether you are a scuba diver, welder, or medical professional, Eureka Oxygen has the gas you need.
If you are an experienced welder, you know that nothing about it is really simple: combustible gases; inert gases (each at disparate appropriate temperatures and flow rates); matching cutting torch tips and flow rates to metal thicknesses; delivering dependable wire feed for MIG with appropriate inert flow. The list goes on, but so does the list of first-rate equipment, supplies, and cylinder gases available at Eureka Oxygen. If you are going to weld, everything you need is available at Eureka Oxygen. We have first-rate equipment, supplies, and cylinder gases, as well as experienced professionals to lend a hand.

For Extraction

The legalization of recreational cannabis is changing the landscape of the California market, and Eureka Oxygen is changing with it. If you are producing cannabis extracts in Northern California, Eureka Oxygen is your number one resource for solvents. Our selection of industrial gases gives you plenty of options for the extraction of cannabinoids.

As Northern California’s leading welding gas supplier, we are well-equipped to meet the needs of the growing cannabis market, especially within the world of concentrates. We offer everything you need for making cannabis oil safely and effectively, including Butane tanks, ISO Butane Blends, CO2 tanks, and cylinder gas refills.


...And For Fire Suppression!

 Some of our cannabis extraction options include:

  • Dry ice (CO2) DIY supercritical CO2 oil extraction
  • Butane (local restrictions apply) for BHO (Butane Hash Oil)
  • Propane for PHO (Propane Hash Oil)
  • Isopropyl Alcohol for Quick Wash
  • Isopropyl Extract (QWISO)
Eureka Oxygen carries a wide selection of equipment for any fire suppression needs. We carry fire extinguishers, exit, and emergency lighting, fire hoses and reels, smoke and carbon monoxide detectors, cabinets and covers, and k-type extinguishers. We also inspect, test and certify fire extinguishers, and inspect and service commercial kitchen exhaust systems.
