What it is

The Andrews O-ring P25.5 is a sealing component for Andrews water heaters, supplied under part number E761. It seals a joint or connection within the appliance to stop water escaping. It is listed for the Andrews Fastflo range of water heaters.

Signs this part needs replacing

Before you order
