What it is

This is a flange gasket manufactured by Ideal, supplied under part number 177270. It is sized for DN100 pipework with a PN6 pressure rating, so it seats between mating flange faces on that nominal bore and pressure class to form a tight joint. It is listed for Ideal Commercial appliances.

Signs this part needs replacing

  • A visible weep or drip at the flange joint, especially once the system is up to temperature and pressure
  • Water staining, crusting or corrosion tracking around the flange faces
  • A gasket that has hardened, cracked or flattened across its sealing face
  • A gasket that has been disturbed or damaged during dismantling of the joint
  • Persistent seepage that returns shortly after the flange bolts are re-torqued

Before you order

  • Confirm the pipework is DN100 and the joint is rated PN6 before matching this gasket to the flange
  • Check the part number on the existing gasket or the appliance documentation against 177270
  • Verify your appliance against the compatibility list, as this gasket is listed for Ideal Commercial equipment only
  • Isolate and drain down the relevant section of the system before breaking the flange joint
