Safeguard your Cat Pump against overheating with this 1/4 inch Thermosensor, a valuable protective component that releases water when it gets too hot during bypass operation. When your pressure washer idles in bypass with the trigger off, recirculating water can heat up quickly and threaten your pump, and this thermosensor helps prevent that by venting hot water before temperatures reach damaging levels. Adding this simple device is an easy way to extend the life of your Cat Pump and keep your equipment running dependably through extended jobs. Sized with a 1/4 inch fitting for Cat Pump applications, it installs easily and delivers meaningful protection for your gear. It is a smart choice for detailers, shops, and operators who want to protect their investment and minimize downtime. Matching the correct fitting to your pump ensures a proper connection. Pair it with quality RCP pump components and accessories to keep your washing system protected.
