Honeywell 43196000-038 Temperature Kit R-410A preventing nuisance trips and furnaceThe Honeywell 43196000 038 High Temperature Kit is a critical accessory for Honeywell ML6421B and Honeywell ML7421B linear actuators requiring enhanced thermal protection. Engineered specifically for actuators with 1 1 2" stroke (38 mm), this field installable kit acts as a thermal barrier, increasing the maximum operating fluid temperature to 428 degrees Fahrenheit (220C). This makes it essential for high pressure steam and hot water applications
