What it is

Before you order

  • Check the part number 5142581 against the appliance identification plate or the existing component before ordering.
  • Confirm the R603 IP reference in the product name matches the appliance documentation.
  • Check whether the gasket supplied with this item suits the joint being remade, so any additional sealing parts can be identified at the same time.
