What it is

The Baxi 95605132 is a large plastic backnut supplied for unvented Baxi appliances. It is a threaded securing nut that holds a fitting or connection tight against a boss on the appliance, so the joint stays sealed under normal operating pressure. As a moulded plastic component it is a serviceable item rather than a permanent one, and it is replaced when the thread or body is damaged.

Signs this part needs replacing

  • Visible cracking, splitting or crazing in the plastic body, particularly around the thread
  • Stripped or cross-threaded threads so the nut will not run down cleanly
  • Weeping or a slow drip at the joint after the nut has been tightened
  • The nut backs off or fails to hold torque once the appliance is up to pressure
  • Brittle or discoloured plastic on an older installation, which can fail on removal

Before you order

  • Confirm your appliance model against the compatibility list, and check the GC number on the data badge where one is shown
  • Compare the thread and diameter of the existing backnut with this large unvented type before fitting
  • Inspect the washer or seal at the same joint and renew it if it is hardened, flattened or damaged
  • Unvented cylinder work should be carried out by a competent person in line with the manufacturer's instructions
