What it is

This is the lower screwed joint gasket on the gas pipe, supplied by Potterton for its commercial boiler range. It sits at the lower screwed connection on the gas pipe run, where it seals the joint against gas escape. The gasket is listed for appliances in the 30 kW to 40 kW band.

Signs this part needs replacing

  • A smell of gas at or around the lower screwed joint on the gas pipe
  • Detection of a leak at the joint during a tightness test or leak detection check
  • Visible damage, flattening, cracking or hardening of the gasket material
  • Disturbance of the joint during service work, where the gasket cannot be reused

Before you order

  • Confirm the appliance model is a Potterton Commercial Paramount Three, Four or Five, as listed
  • Confirm the appliance output matches the 30 kW or 40 kW fitment listed
  • Check the existing gasket position is the lower screwed joint on the gas pipe
  • Gas-carrying joints must be reassembled and tested by a Gas Safe registered engineer
