What it is

The Popular Oil Spares nipple 3/8M x 1/4M cone is a threaded reducing nipple used within oil-fired boiler equipment. It has a 3/8 male thread at one end and a 1/4 male cone connection at the other, allowing two different thread sizes to be joined in the oil line. It is listed within the Popular Oil Spares oil spare parts range.

Signs this part needs replacing

  • Oil weeping or staining around the threaded joint
  • A fuel smell or dampness at the nipple connection
  • Corrosion, pitting or flattened threads on either end
  • Difficulty achieving an oil-tight seal after reassembly
  • Cross-threading or deformation caused during removal

Before you order

  • Confirm both thread sizes on the existing nipple: 3/8 male and 1/4 male cone
  • Inspect the mating cone seat for damage before fitting a new nipple
  • Check the part against the manufacturer's parts list for your appliance model
  • Confirm whether a sealing washer or jointing compound is used on the cone seat
