OATEY P9803E Dearborn® 1.5-in. x 16-in. Double Flanged Strainer Tailpiece

Both ends of the Dearborn P9803E are 1-1/2 inch slip joint inlets, so it mates to standard 1-1/2 inch slip joint tubular drain parts at either end with a nut and washer. There is no threaded or glued end to work around, which is why it drops into an existing 1-1/2 inch waste run without reworking the trap.

Yes, the P9803E is made to be cut to length. It ships at 16 inches, and you trim the end back to whatever drop your cabinet and disposal height need. That is the usual way it gets used: order long, cut on site, then set the slip nut over the cut end.

The P9803E meets ASTM F 409, the standard for thermoplastic tubular drain fittings, and it is IAPMO listed. Those are the two things an inspector or a spec writer normally asks for on tubular waste under a sink, so it can be submitted on jobs that call for listed tubular drainage.

A double flanged tailpiece like the Dearborn P9803E is the piece for it. It is called out for disposal applications where two tailpieces are needed, with a flanged slip joint end at both ends rather than one flanged end and one plain. If your setup only needs a single drop off the basket strainer, a standard single flanged tailpiece is the simpler part.

Four lengths are made in this Dearborn tailpiece line: 6 inch, 8 inch, 12 inch, and 16 inch, all in 1-1/2 inch. The P9803E is the 16 inch. If you are standardizing a building, buying the 16 inch and cutting covers every shorter drop, which is why maintenance carts usually carry the long one.

The P9803E is white. Under a cabinet that is fine and it is what most kitchen disposal work uses. For an exposed ADA lavatory or an open-front fixture where the trap and tailpiece are visible, buyers normally go to a chrome plated brass tubular tailpiece instead, since the white plastic is a concealed-work part.
