What it is

The Vaillant 133627 test nipple, cpl., is a gas boiler spare used at the test point on the appliance. It is supplied as a complete assembly for the Vaillant Thermocompact and Turbomax Plus ranges. The nipple provides the connection point used when checking gas inlet pressure during commissioning and servicing.

Signs this part needs replacing

  • Gas smell or a detectable leak at the test point during a tightness test
  • Visible corrosion, cracking or distortion of the nipple
  • Damaged or rounded hex, making the nipple difficult to tighten or remove
  • The test point will not seal after a pressure reading has been taken
  • Thread damage preventing a gas-tight connection to the test gauge

Before you order

  • Confirm the appliance model and variant against the data badge before ordering
  • Check the manufacturer part number 133627 matches the number shown in the appliance parts list
  • Confirm whether the test point on your appliance uses the complete assembly
  • Isolate the gas supply and follow safe gas working practice when fitting
