Inlet Connector: QCC1/Type1 Product Details: 2PCS Propane Tank Gauge Materials: High quality 100% solid brass + plastic NOTICE: Will not read levels immediately; begins working when propane is flowing. Provides excess flow protection in case of a broken gas line and thermal protection in case of fire. To use as a leak tester, turn off all propane appliances, open and close the tank valve, then wait to see if the pressure drops. If pressure decreases, a leak is present. The propane tank gauge level indicator helps monitor LP tank levels, preventing unexpected fuel depletion during use. Useful for troubleshooting—if you have a weak flame but the gauge reads in the green zone, the issue likely lies elsewhere. Can also function as a leak detector: turn off all propane appliances, open and close the tank valve, then observe for pressure drop. A drop indicates a leak. For safety: All propane appliances such as grills, lanterns, heaters, and stoves are intended for outdoor use only. Ensure connections are fully tightened at both the propane tank and appliance ends before use to prevent gas leakage.
