System Sensor ST-5 Sampling Tube deep pitting or damaged ceramic

deep pitting or damaged ceramic insulators require a full replacement of the 62390-002 assembly to ensure safety

Ensures consistent frost removal to maintain high COP (Coefficient of Performance) in cold climates

effectively minimizing frictional resistance and supporting accurate gas delivery at low pressure differentials

the 8406-037BX is technically identical to the 8406-037 in form

System Sensor ST-5 Sampling Tube deep pitting or damaged ceramicThe System Sensor ST 5 is a 5 foot metal sampling tube engineered for high performance smoke detection in HVAC ducts ranging from 4 to 8 feet in width. Built with a durable rigid steel construction, this tube is essential for contractors installing or maintaining duct smoke detectors in commercial and industrial air handling systems. The ST 5 acts as the direct replacement for L 313 1, ensuring seamless integration into legacy systems without the need
