What it is

The Spring Tightening Clamp - 23.1mm is a spring-style retaining clamp supplied by Potterton for Potterton Commercial boiler applications. It is listed under part number 5142405 and is used to secure a 23.1mm diameter connection or component within the appliance. The clamp relies on spring tension rather than a threaded fastener to hold the joint.

Signs this part needs replacing

  • Visible corrosion, pitting or surface cracking on the clamp
  • Clamp has lost tension and no longer grips the connection securely
  • Weeping or moisture tracking at the joint the clamp retains
  • Clamp distorted or deformed from removal or previous service work
  • Clamp missing or found loose within the appliance casing

Before you order

  • Confirm the connection diameter measures 23.1mm before fitting
  • Check the appliance model against the Sirius 2 and Sirius 3 listings above
  • Inspect the mating component and joint for damage before refitting
  • Verify the existing clamp's condition to confirm replacement is required
