What it is

The Sime Teflon short spacer for the MPMV 3315 valve assembly is a small PTFE seating component used within the valve on Sime Format series gas boilers. It sits in the valve assembly to provide a low-friction, chemically resistant seal face between mating parts. The spacer is supplied under Sime part number 6223902.

Signs this part needs replacing

  • Visible water or gas-side staining around the valve assembly joint
  • Weeping or a persistent drip from the valve body area
  • The spacer is deformed, flattened or has taken a set
  • The spacer feels hard, brittle or shows cracking at the edges
  • Recurring leaks after the valve has been disturbed during service

Before you order

  • Confirm the boiler model against the fit list above
  • Check that the valve assembly is the MPMV 3315 type
  • Inspect the spacer seat and mating faces for damage before refitting
  • Check whether any other seals in the valve assembly also need renewing
