Finlandia / Harvia Part # F48 Rubber Bushing (Grommet) Thermostat tubing runs inside to protect the sensing line as it passes through metal panels in F-1T, F-2T, and F-2 control systems. This dedicated rubber grommet cushions the thermostat tubing from sharp edges and vibration, helping prevent kinks, abrasion, or leaks that can affect temperature accuracy. Made from heat-resistant material suited to sauna environments, it maintains flexibility and sealing performance even under prolonged exposure to warm, humid conditions. By preserving a snug, insulated passage for the capillary or sensor tube, the F48 supports stable heater regulation and long-term reliability of your controls. Easy to install during new builds or service work, it is a small but important detail in maintaining safe, professional-quality Finlandia and Harvia control installations.
