Ideal Screwed Flange PN6 2 Inch 177326

The Ideal 177326 is a screwed flange with a 2 inch threaded bore and a PN6 nominal pressure rating, produced by Ideal as a spare for its commercial appliance range. It forms the bolted, threaded joint where pipework connects to an appliance or system component, with the flange face sealing against a mating face and the threaded bore accepting a 2 inch male thread. PN6 denotes a nominal pressure rating of 6 bar, which suits low-pressure commercial heating and water circuits.

• Weeping or dripping at the flange joint while the circuit is at normal working pressure
• Visible corrosion, pitting or scale build-up on the flange face or around the bolt holes
• A damaged or scored sealing face that will not pull up tight against the mating flange
• Cracking, distortion or thread damage in the flange casting
• Bolts that need repeated re-tightening to hold a seal

• Confirm part number 177326, or the alternative number 1180499, against the parts list for your appliance.
• Check the connection size and pressure rating match the pipework being joined: 2 inch, PN6.
• Inspect the mating gasket and bolts before refitting, as a flange joint that has been broken down may need new sealing components.
• Verify the appliance model in the compatibility list below, as the same part number can appear across several build variants.
