Hamworthy Gasket 135 Dia x 100mm x 4mm 573405186

This is a water connection gasket manufactured by Hamworthy, supplied in a nominal size of 135 diameter x 100mm x 4mm. It seals the water connection joints on Hamworthy Shaftesbury floor standing gas boilers, preventing leakage at the mating faces. The gasket is a service item that is replaced whenever a joint is broken or a weep develops.

• Weeping or dripping at the boiler water connection with the appliance running or under pressure
• Damp staining, corrosion or limescale tracking around the connection flange
• The joint has been disturbed during servicing or component replacement
• The old gasket is flattened, hardened, cracked or shows a split

• Confirm the appliance model from the data badge, as fitment covers the Shaftesbury He range only
• Check the existing gasket size and profile against the 135 x 100 x 4mm dimensions before ordering
• Inspect the mating faces for pitting, scale or distortion, as a damaged face will not seal with a new gasket alone
• Isolate and drain or depressurise the water connection before removing the old gasket
