Common Questions

Is this valve certified for Natural Gas?

Yes -- this Chicago Faucets fitting is built and indexed for Natural Gas service (index button/label: GAS). It is not interchangeable with a fitting indexed for a different medium: laboratory gas fittings are certified per-service, so swapping a valve between gases is a code violation, not just a labeling mismatch.

Does this have backflow protection?

Yes -- it ships with integral check valve. This matters whenever a hose can be submerged in a vessel or chemical: without backflow protection, a drop in supply pressure can siphon contaminated liquid back into the potable/gas line.
