What it is

The Alpha 6.5201351 is a 1/2 inch BSP brass cap used on Alpha Ocean Style gas boilers. It closes off a threaded 1/2 inch BSP port on the appliance, sealing the connection against escape of water or gas. The brass body resists corrosion in the damp conditions found inside a boiler casing.

Signs this part needs replacing

  • Weeping or dripping from the capped connection
  • Water staining, scale or corrosion around the cap
  • Rounded or damaged hex flats, making the cap difficult to remove
  • Visible cracking or pitting on the brass body
  • The cap will not tighten down or sits loose on the thread

Before you order

  • Confirm your appliance model against the fit list above
  • Check the port you are capping is 1/2 inch BSP
  • Inspect the mating thread for damage or cross-threading before fitting
  • Check whether a washer or sealing compound is needed to complete the joint
