Kit contains:

  • Expansion vessel
  • Pressure relief valve
  • Fibre washer

GasPart Vessel Kits make boiler pressure issue repairs as easy as possible. Kit includes expansion vessel, pressure release valve and washers where required.

Good practice suggests replacing a PRV at the same time as a faulty vessel. A faulty vessel can cause damage to the PRV resulting in the boiler still showing a low pressure fault. Buying both together is simple and will help eradicate further problems.
