Choosing and fitting
When selecting a replacement hose of this type, verify the inner and outer diameters (5 mm and 9 mm respectively) and the temperature rating to match the original. Ensure the hose is cut to the correct length and pushed fully over the connection, then secured with a worm-drive clip or spring clamp. Check wall thickness and flexibility to avoid premature failure.
Signs of failure
Hoses of this kind may degrade due to high temperatures, leading to cracks or hardening. Symptoms include leaks at connections, reduced system pressure, or visible damage near the heat exchanger or flue gas path. Inspect the hose for signs of wear, especially in areas exposed to heat.
