What it is
The Andrews O-ring S38 (part number Z356) is a sealing ring for Andrews water heaters and hot water spares. It seals joints and connections within the appliance to prevent water loss. It is listed for use across the Andrews Fastflo and WH water heater ranges.
Signs this part needs replacing
- Water weeping or dripping from the joint the O-ring seals
- Visible cracking, splitting or perishing of the rubber
- A hardened or flattened O-ring that no longer seals under compression
- Scale or debris build-up around the seal causing a poor fit
- Leaks that return after the joint has been tightened
Before you order
- Confirm your appliance model against the fitment list above
- Check the part number Z356 or the S38 size marking on the existing O-ring
- Verify the O-ring is the correct seal for the joint you are repairing
- Inspect the mating surfaces for damage or scale before fitting
