What it is

The Hamworthy 573405175 is an O-ring seal supplied as an intersection water seal for the manufacturer's Shaftesbury He range of floor standing gas boilers. It seals the water-carrying joint where the sections or intersecting waterways meet, preventing weeping and loss of system pressure at that point.

Signs this part needs replacing

  • Water weeping or tracking from the intersection joint during operation
  • Visible hardening, flattening, cracking or perishing of the existing O-ring
  • Scale or corrosion deposits embedded in the seal face
  • A joint that continues to leak after the retaining components have been correctly tightened
  • Pressure loss on the heating circuit traced to the sealed joint

Before you order

  • Confirm the appliance model against the data plate, as the Shaftesbury He range covers several outputs
  • Check the part number 573405175 against the existing seal or the manufacturer's literature
  • Inspect the mating surfaces and seal seat for pitting, scale or corrosion before reassembly
  • Confirm how many seals the joint requires, as more than one may be needed
