What it is
The S212327 is a red SIL70 O-ring flue seal manufactured by Glow-worm. It seals the flue connection on Micron FF gas boilers, preventing flue gases from escaping at the joint. It is a serviceable sealing component supplied as a single O-ring.
Signs this part needs replacing
- Visible cracking, flattening or hardening of the O-ring
- Flue joint showing signs of leakage or staining
- Seal deformed or compressed so it no longer sits correctly in its groove
- Combustion readings outside the expected range at the flue
- Seal damaged or displaced during flue removal or servicing
Before you order
- Confirm the boiler model against the fitment list above
- Check the existing seal for colour and material marking before removal
