What it is

The Hamworthy 179508 is a DN100 (4") PN16 gasket manufactured to BS7351. It is a sealing component used on flanged joints within Hamworthy appliance and pipework assemblies, sized to suit nominal bore DN100 connections at PN16 pressure rating.

Signs this part needs replacing

  • Visible weeping or drips at the flanged joint under normal operating pressure
  • Gasket material showing cracking, hardening, swelling or delamination
  • Flange faces showing traces of water tracking or corrosion staining around the joint
  • Gasket compressed or deformed beyond its original thickness after removal
  • Repeated re-torquing of the flange bolts fails to stop the leak

Before you order

  • Confirm the flange nominal bore is DN100 (4") and the system rating is PN16
  • Check the existing gasket against the BS7351 designation before ordering
  • Verify the Hamworthy appliance or assembly model against the manufacturer's parts list
  • Confirm the flange face type and bolt hole arrangement suit the gasket supplied
