Sime Fibre Sealing Cord 6326945

The Sime 6326945 is a fibre sealing cord used on Sime Murelle ONE HE 25 appliances. It forms a heat-resistant seal at the joint where it is fitted, closing the gap against flue gases, condensate or air movement depending on the application. Fibre cord of this type is a consumable item and is renewed whenever the joint it seals is opened.

• The cord is flattened, hardened or brittle and no longer springs back when compressed
• Visible fraying, crumbling or loss of material along the cord
• Staining, soot marks or condensate weeping around the joint it seals
• The joint has been disturbed during servicing or repair and the old cord cannot be reused
• Combustion readings or flue gas analysis drift outside the expected range after reassembly

• Check the appliance data plate to confirm the model and GC number match the fitment listed above
• Confirm the part number 6326945 against the manufacturer's parts list for your appliance
• Check how many joints require sealing, as more than one length may be needed
• Inspect the joint faces for damage before fitting, as a scored or distorted face will not seal correctly
