What it is
The Glow-worm S208737 is a clear silicone tube measuring 40mm, used on the air pressure switch circuit of a range of Glow-worm appliances. It forms the flexible connection between the pressure switch and the fan or flue sensing point, carrying the pressure signal that proves airflow before the boiler fires. Silicone construction keeps the tube flexible and stable where heat and repeated flexing would harden ordinary tubing.
Signs this part needs replacing
- The tube has hardened, cracked or split, allowing the pressure signal to leak
- The tube has collapsed or kinked, restricting the pressure signal to the switch
- The tube has come loose or no longer grips the switch or fan spigot
- The bore is blocked with debris, dust or condensate
- The appliance locks out or the pressure switch fails to prove, with the tubing as the suspected cause
Before you order
- Confirm your appliance model against the fit list above before ordering
- Check the existing tube's length and bore match the 40mm silicone tube specified here
- Inspect the switch and fan spigots for damage or wear while the tube is removed
- Verify the part number S208737 against the manufacturer's parts list for your model
