Maintains factory-specified gas-to-air mixing ratios for clean combustion

open construction design that allows for immediate installation onto 1/4-inch flare fittings without the need for additional mounting brackets

The orifice requires a 1-inch thin-wall hex socket wrench for removal and should be torqued to 50-60 ft-lbs upon re-installation to achieve a secure seal within the cast iron body

including 2-stage upflow and horizontal variable speed models

Operating with a normally closed configuration

Field Controls 46082700 Adapter Maintains factory-specified gas-to-air mixing ratiosThe Field Controls 46082700, also known as the Model TCA 1 Thermocouple Adapter, is a specialized pilot safety component designed for gas fired heating systems utilizing a Right Hand Thread configuration. This adapter acts as a critical interface, allowing for the integration of standard thermocouples into existing safety circuits or powerpile systems without necessitating a full valve replacement. Engineered for high temperature resilience and
