Bosch Hvac 7098266 Sealing 10-Pack

The Bosch HVAC 7098266 Sealing 10X provides a pressure-tight barrier at pipe joints, port connections, and threaded fittings, preventing fluid or gas leakage at essential interface points within the HVAC system. Each seal compresses against the mating surface when the fitting is tightened, conforming to minor surface irregularities and maintaining a consistent closure under the thermal expansion and pressure cycling that occurs during normal operation. Used at water inlet and outlet connections, service ports, and valve assemblies across condensing boilers and hydronic distribution, the seals fit directly onto the indicated sizing without additional preparation or sealing compounds.
