What it is

The Warmflow 631 is a washer with a 13mm internal diameter and a 2mm thickness, supplied for Warmflow oil combi appliances. It seats at a joint to form a seal and stop weeping under pressure. This is a small consumable part typically replaced during service or repair work.

Signs this part needs replacing

  • Dampness or weeping around the joint the washer seals
  • Visible flattening, cracking or perishing of the washer
  • A drip or slow leak at the union that returns after tightening
  • Staining or residue beneath the joint

Before you order

  • Confirm the washer measures 13mm internal diameter and 2mm thick
  • Check your appliance model against the manufacturer's parts list
  • Check how many washers the joint requires before ordering
