OATEY P9801 Dearborn® 1-1/2 in. x 8 in. Flanged Strainer Tailpiece

Yes. The P9801 Dearborn tailpiece is 1-1/2 in. x 8 in. and is flanged on one end specifically for connection to a sink strainer, so it drops into a standard 1-1/2 inch strainer body with the strainer's slip nut and washer. Oatey calls this a Hi-Line (flanged) connection. The flange seats under the nut at the strainer; the plain end goes down into your trap adapter or P-trap inlet.

The P9801 is IAPMO Listed and meets ASTM F409, the standard covering thermoplastic accessible and replaceable plastic tube and tubular fittings. Those are the two marks an inspector looks for on a plastic tubular drain component, and they are what lets it be specified on institutional and multi-family work rather than only residential.

It should. The Dearborn P9801 is a universal design on the 1-1/2 inch tubular size, which is the standard kitchen and utility sink drain size in North America, so it is not tied to a particular sink or strainer brand. For a property manager stocking a truck or a maintenance shop, that means a single tailpiece part number covers most 1-1/2 inch strainer installs across a mixed fleet of fixtures.

Usually not. At 1-1/2 inch, this tailpiece matches kitchen, utility and bar sink drains. Bathroom lavatories in North America are typically 1-1/4 inch, and a lavatory pop-up assembly comes with its own tailpiece attached to the drain body, so a separate flanged strainer tailpiece is not what that fixture takes. Match the tube size stamped on your existing trap before ordering.

No, and it is the distinction that decides which one you order. The P9801 is flanged (Oatey calls it Hi-Line) on the strainer end, so the tube end is belled out and the strainer nut clamps down on that flange. A slip-joint tailpiece is straight tube on both ends and seals with a washer. If you pull out the old tube and see a flared lip at the top, this is the replacement; if both ends are plain, you want the slip-joint type instead.

Model P9801 itself is the 8 inch length. The same Dearborn flanged tailpiece is made in 4 in., 6 in., 8 in. and 12 in. If the gap between your strainer and the trap inlet is short, the 4 or 6 inch avoids cutting; if you have a deep cabinet or a low trap arm, the 12 inch gives you room. An 8 inch tailpiece can also be cut down to length on the plain end.

For a concealed cabinet drain, yes. The P9801 is polypropylene, which will not corrode or pit the way thin-wall chrome tube does, and it is the usual choice where the trap is hidden behind a cabinet door. Where the drain is exposed, on a wall-hung lavatory or a pedestal sink, buyers normally go chrome-plated brass for appearance. Function is the same either way.

The P9801 is the tailpiece tube only. The nut and washer at the strainer end are normally the ones supplied with the sink strainer, and the connection at the trap end uses the slip nut and beveled washer that come with your P-trap or trap adapter. If you are building a drain from loose parts rather than replacing a single tube, order the trap and strainer with their nuts and washers.

White. Dearborn makes this flanged tailpiece in white or black polypropylene, and P9801 is the white version. The two are the same part functionally; color only matters if the drain is visible or if your building standard calls for one.
