Ideal Plug 1/2 Inch No 290 069099

The Ideal 069099 is a 1/2 inch threaded plug, listed by the manufacturer as plug No 290. It is a small closure component that screws into a threaded port on the appliance to seal that opening against water or system pressure.

It belongs to the Ideal Commercial Buccaneer family of appliances, a range of commercial gas and oil boilers and combi units. Plugs of this type are typically removed during servicing or component replacement to drain, vent or gain access to an internal passage, then refitted to restore a pressure-tight joint.

• Visible weeping or a damp stain around the plug after the appliance has run up to temperature
• Corrosion or pitting on the plug head or threads, making it difficult to remove or refit
• Scale or debris on the threads preventing the plug from seating properly
• A plug that has been cross-threaded or over-tightened and no longer seals
• Unexplained loss of system pressure traced to the plug position

• Confirm the appliance model and, where shown on the data badge, the GC number against the compatibility list
• Check the number on the old plug against 94950110, as earlier builds used this reference
• Inspect the mating thread and seating face while the plug is out; a damaged thread will not seal with a new plug alone
• Have the correct sealing method to hand for refitting, as the plug relies on a sound joint at the seating face
