What it is

This is a pack of 10 water assembly inlet union O-rings manufactured by Morco Products. The O-ring seals the inlet union connection on the water assembly, preventing water loss at the joint. It is supplied as a multi-pack for servicing or stock use.

Signs this part needs replacing

  • Water weeping or dripping from the inlet union joint
  • Visible hardening, flattening or cracking of the existing O-ring
  • Scale build-up or deformation on the sealing face of the ring
  • Leakage returning after the union has been re-tightened

Before you order

  • Confirm the appliance model matches one of the listed fitments
  • Check the existing O-ring against the replacement before fitting
  • Confirm whether a pack of 10 suits the job at hand
  • Inspect the union faces for damage or scale before refitting
