What it is

The Sime O-ring 3068 (part number 6226412) is a sealing ring with a 13.1mm diameter. It is fitted to the flow and return pipe connections on Sime gas boilers, where it seals the joint against water leaks.

Signs this part needs replacing

  • Water weeping or dripping at the flow or return pipe joint
  • Damp staining or corrosion around the connection
  • The O-ring looks flattened, cracked or hardened
  • Scale or debris embedded in the seal
  • Boiler pressure dropping with no other visible cause

Before you order

  • Confirm your boiler model and GC number against the fitment list
  • Check the O-ring is for the flow or return pipe connection
  • Verify the 13.1mm diameter matches the seal being replaced
  • Check how many O-rings the joint requires
