What it is

The Andrews O-ring JASO 2028A, part number Z363, is a sealing component for Andrews water heaters. It is manufactured to the JASO 2028A specification and provides a watertight seal at the joint where it is fitted. It is listed for use across the Andrews Fastflo and hot water spares range.

Signs this part needs replacing

  • Water weeping or dripping from the joint the O-ring seals
  • Visible cracking, flattening or perishing of the ring
  • The ring has hardened and no longer sits proud of its groove
  • Water staining or mineral deposits around the joint
  • A leak that returns shortly after the joint is reassembled

Before you order

  • Confirm your appliance model against the fits list above
  • Check the existing O-ring is specified as JASO 2028A
  • Inspect the sealing face and groove for damage before fitting a new ring
  • Isolate and drain the appliance where the joint requires it
