OATEY 1101B – Frequently Asked Questions

1) What is the Oatey 1101B Dearborn flange used for?
It is an escutcheon-style flange that covers the ragged wall or floor opening where a supply tube penetrates. Slide it over the 1/2 inch copper stub-out and it hides the hole and the cut drywall edge behind the stop valve. It is chrome plated, so it suits exposed work under lavatories and at toilet supplies.
2) Does the Oatey 1101B flange thread onto a 1/2 inch NPT nipple?
The 1101B is designated a 1/2 inch NPT flange, so it is sized to the 1/2 inch NPT trade size. In practice it is used as a cover at the penetration rather than as a pressure-carrying fitting, and the 7/8 inch opening lets it pass over 1/2 inch CTS copper.
3) Is the Oatey 1101B chrome or plastic?
Chrome plated metal, not plastic. That matters on finished walls in apartments and hotel baths where the flange stays visible next to a chrome angle stop and a plastic escutcheon would look off.
4) What part number do I order for the Dearborn 1/2 inch NPT flange?
Order Oatey manufacturer part number 1101B. It is a single model, so there are no finish or size options to specify.
5) Is the 1101B flange light enough to stock in quantity for a maintenance cart?
Yes. Each 1101B flange weighs 0.025 and takes 0.01 volume as catalogued, so a property maintenance team can carry a box of them without much bulk. Tubing and the stop valve are separate items.
