Slant Fin 790-099-000 Immersion Well 1/2" NPT X 1.5"

The Slant Fin 790-099-000 Immersion Well is a temperature sensor housing component used in boiler and heating systems. It allows a temperature probe or control sensor to measure fluid temperature without direct contact with the circulating water. It provides a sealed pathway into the system piping or boiler body with 1/2" X 1.5" NPT connections while protecting the sensor from pressure, flow, and corrosion. It is commonly used in hydronic heating equipment within HVAC systems, where accurate temperature monitoring is required for control operation, safety limits, and system regulation. Within the assembly, it supports stable sensors.
