What it is

The Ideal 004556 is a 3/8 inch bulkhead locknut made in brass, supplied by Ideal for its commercial appliance range. It threads onto a bulkhead fitting to clamp the assembly against the casing panel and hold the joint tight. Brass is used because it resists corrosion in the damp conditions found around appliance connections.

Signs this part needs replacing

  • Weeping or dripping at the bulkhead where the pipe passes through the casing
  • Water tracking along the pipe, or staining and scale on the panel around the fitting
  • Locknut seized, cross-threaded or rounded off so it can no longer be tightened
  • Corrosion, pitting or green discolouration on the brass
  • A joint that will not pull up tight even after the seal has been renewed

Before you order

  • Confirm the appliance model and serial number against the compatibility list
  • Check the thread size and material of the existing locknut match the 3/8 inch brass item listed here
  • Inspect the sealing washer or gasket at the same joint and renew it if it is perished
  • Isolate and drain the appliance before disturbing the fitting
