The thermostat kno b stop is used on Minimax/Minimax Plus/PowerMax Thermostat Knob Stop applications and helps limit knob travel and maintain the intended adjustment range. It is a useful replacement when the existing part is cracked, corroded, stripped, distorted, leaking, missing, or no longer holding the correct operating position.Accurate replacement parts are important on legacy systems because small differences in diameter, thread style, or mounting geometry can affect sealing and alignment. This part is best suited for precise repairs where the matching OEM-style part number, 470414, is the main guide for compatibility.
