What it is

The Riello 3003873 is a pressure test nipple listed for Riello oil boiler and burner spares. It provides a test point for pressure checks on compatible Riello burners. It is listed for use with the Riello RS and RLS burner families.

Signs this part needs replacing

  • Leakage or weeping at the pressure test point
  • Damaged or crossed threads on the nipple
  • Rounded or damaged hex flats, making removal or tightening difficult
  • Corrosion or blockage preventing a stable pressure reading
  • The nipple no longer seals correctly when the test port cap or gauge is fitted

Before you order

  • Confirm the burner model and code match the fitment list.
  • Check the existing part is marked 3003873 or matches the listed Riello part number.
  • Inspect the thread and sealing face on the burner before fitting.
  • If the burner model is not listed, check the manufacturer's parts list for the correct pressure test nipple.
