What it is

This is an O-ring supplied by Main for the selector screw and spindle on the water valve. It forms the seal at that point on the valve assembly, preventing water from escaping past the spindle. It is listed under water heater spares for the Main Multipoint BF range.

Signs this part needs replacing

  • Water weeping or dripping from around the selector screw or spindle
  • Dampness or corrosion staining on the water valve body
  • The O-ring appears flattened, hardened or cracked
  • Scale or debris trapped at the seal face causing a poor seal

Before you order

  • Confirm the appliance model against the data badge before ordering
  • Check the O-ring is the correct seal for the selector screw / spindle position on the water valve
  • Inspect the spindle and seating for wear or damage that could affect the new seal
