What it is

A 2" BSP cap for the gas manifold, supplied by Hamworthy for its Modumax floor standing boiler range. The cap seals the manifold connection point, closing off the thread so the gas path remains gas-tight. It is a service part intended for fitting by a competent heating engineer working on the appliance.

Signs this part needs replacing

  • Gas odour around the manifold or at the cap itself.
  • Leak detection fluid bubbling at the cap thread with the gas supply on.
  • Visible corrosion, cracking or cross-threading on the cap.
  • A gas tightness test failing at the manifold cap.

Before you order

  • Confirm the appliance is one of the Hamworthy Modumax floor standing models listed.
  • Check that the manifold connection is a 2" BSP thread before ordering.
  • Quote part number 742221184 when checking the requirement against the appliance.
  • Gas work on the manifold should be carried out by a competent, registered engineer.
