The Regulator Replacement Gauge is designed for precise pressure monitoring on both oxygen and fuel gas regulators. Each UL-listed gauge features a polished brass case, steel dual-scale dial, and a clear polycarbonate threaded lens for durability and easy readability.

These gauges are ideal for gas distribution systems using non-corrosive gases such as oxygen, propane, or acetylene. The “Use No Oil” marking ensures safe use in oxygen applications.

The 4000 lb replacement gauge measures the inlet pressure on oxygen regulators.

The 200 lb replacement gauge measures the outlet pressure on oxygen regulators.

The 400 lb replacement gauge measures the inlet pressure on propane or acetylene regulators.

The 30 lb replacement gauge measures the outlet pressure on acetylene regulators.
