OATEY 8482 Dearborn® 1-1/4" 90 Degree Slip Joint Elbow, Chrome - 20 Ga.

No, they come with it. The 8482 ships with 2 zinc slip joint nuts and 2 rubber washers, one set per end, so the elbow is ready to install out of the box. You only need a tube cutter and a bit of tubing if you are trimming the run.

It is 20 gauge brass tubing with a chrome finish. The chrome is a plating over the brass, so the wall itself will not rust the way a plated steel fitting does. The 20 gauge wall is the lighter of the common tubular weights, which suits residential and light commercial lavatory drains rather than heavy use exposed work.

Use the elbow when the drain outlet and the trap arm are offset by a clean right angle and the connection is visible. The 8482 gives you a rigid, chrome finished brass turn that will not sag or collect debris the way corrugated flex tubing does, and because both ends are slip joint you can rotate the fitting to line up before tightening the nuts. Flex tubing is only the better call when the offset is odd or out of plane and you cannot get a rigid run to reach.

No. This is a drain fitting. Slip joint connections seal with a compressed rubber washer and are not rated to hold water under pressure, so the 8482 belongs only on the waste side, between a tailpiece, trap, and trap arm. Use a compression or threaded brass fitting for supply.

Yes, the finish is chrome over brass, which is what exposed tubular drain work under wall hung and pedestal lavatories normally calls for. If the rest of the trap, tailpiece, and escutcheon are chrome, this will match. The visible nuts are zinc, so expect a slight difference in tone at the joints compared to a full chrome nut.

Order it as Oatey Dearborn 8482. It is a single model, no size or finish options to specify, and it weighs 0.34 pounds, so it ships small if you are stocking a truck or a maintenance shop.
