Leak Detection Gauge, 1-1/2″ NPT – The Cary Company

The Leak Type K-1.5 Gauge is a reliable, vertical type leak monitor used for detecting leaks in the annular/interstitial space of a double wall above ground containment tank (AST’s) with a 1-1/2″ NPT bung opening. Its simple mechanical design promotes durability, minimal upkeep, quick installation, and easy/inexpensive repairs. If you have a monitoring pipe or have a threaded fitting at the top of the interstitial space on a double wall containment tank, this monitor will thread right in. Any liquid seeping into the containment space will cause the float to rise which will provide a visual indication on top of the tank that there is liquid in the interstitial containment area.
