Ric. capillare De Dietrich 7884590

Capillary tubes are precision components used in thermostatic controls and expansion valves within heating systems. This Ric capillary is designed to accurately transmit temperature or pressure changes, enabling precise regulation of gas or refrigerant flow. Replacing a worn or blocked capillary can resolve issues like inconsistent temperatures or system lockouts. It is a small but vital part for maintaining the responsiveness and efficiency of your boiler or burner controls.
