Sioux Chief 490-11322 – Frequently Asked Questions
1) What does the Sioux Chief 490-11322 flange support gasket actually do in a toilet rough-in?
It goes between the closet flange and the floor surface, giving the flange a stable seating surface before the toilet is set. The point is keeping flange height consistent across the base, which is where uneven or aging subfloors usually cause trouble. It is a support gasket under the flange, not the wax ring or foam seal that goes between the flange and the toilet horn.
2) Is the 490-11322 the right part if my closet flange is sitting loose or low on the subfloor?
For a flange that needs a supportive seating surface against the floor, yes, that is what the 490-11322 is for. It is used in closet flange installation and replacement, toilet rough-in, and flange leveling and support work. What it is not is a structural repair ring, if the flange itself is cracked or the bolt slots are broken out, you are replacing the flange or adding a repair ring, not gasketing it.
3) How many gaskets come in a pack of Sioux Chief 490-11322?
Ten each per pack. That is the ordering unit, so a service truck or a maintenance shop gets enough for multiple rough-ins and callbacks without breaking down a bulk case. Order quantity 1 means 10 gaskets, not one.
4) What part number and UPC should I order for the Sioux Chief floor flange support gasket?
Sioux Chief manufacturer part number 490-11322, UPC 739236303486. There is a single model, so there are no size or finish choices to specify when ordering.
5) Do I need any special tools to install the 490-11322 gasket?
No. It is placed during flange setting with no special tools required, so it goes in as part of the normal closet flange install sequence rather than adding a step with its own equipment.
6) Where do I find the dimensional and material details for the Sioux Chief 490-11322?
Sioux Chief publishes a spec sheet PDF for the 490-11322 that carries the full dimensional and material data. Worth pulling before you order if you are matching it to a specific flange body or a non-standard floor buildup.
