What it is

The O-RING OUTER UNION BLOCK is a nitrile O-ring from Nuway, listed as OS8 BS110, intended for the outer union block on compatible oil burners. It seals the union joint and prevents fuel weeping at that connection. It is a service item for routine burner maintenance.

Signs this part needs replacing

  • Oil weeping or a damp film around the outer union block joint
  • Fuel smell around the burner casing when the appliance is running
  • A flattened, hardened or cracked O-ring when the union is opened
  • Weeping returns shortly after the union is tightened down

Before you order

  • Confirm the burner model against the fit list above
  • Check the reference on the old seal against OS8 and BS110
  • Inspect the union faces for scoring or damage that would stop the O-ring seating
  • Confirm the replacement is a nitrile O-ring to match the listed material
