Acetylene B-Tank Cylinder Contents Gauge - 1/8" NPT Bottom Mount

Don't Let an Empty Tank Stop the Job

We've all been there—you're in a crawl space or under a sink, ready to braze a copper line, and you realize too late that your B-tank is running on fumes. Or worse, you drop your regulator and crack the gauge face. The Techniweld CCG is the perfect replacement contents gauge to get your Acetylene B-Tank regulator back in action. Designed to fit the standard regulators used by plumbers and HVAC techs, this gauge screws right in and gives you the accurate readings you need to plan your work day.

Direct Fit Replacement
This gauge features a 1/8" NPT bottom mount thread, which is the industry standard for most compact B-tank regulators (like those from TurboTorch, Goss, or Uniweld). Installation is simple: just remove the old gauge, clean the threads, apply a little Teflon tape (being careful not to cover the opening), and tighten the new CCG in place. It’s a quick fix that saves you the cost of buying a whole new regulator.

Clear and Durable
When you are working with acetylene, you need to know exactly what's in the tank. This gauge provides a clear reading of your cylinder pressure, so you know when it's time to swap out bottles. The construction is tough enough to handle the bumps and knocks of a service truck, and the dial is easy to read even in dim lighting conditions. It measures the high-pressure side (contents), typically reading up to 400 PSI, covering the full range of a standard acetylene cylinder.

Safety First
Running a regulator with a broken gauge isn't just annoying; it can be unsafe. A cracked lens can let moisture in, ruining the mechanism, and a bent needle can give false readings. Swapping in a fresh Techniweld CCG ensures your gear is safe, sealed, and ready to burn. Keep one in your toolbox as a backup so you never have to down tools due to a busted gauge.
