OATEY 8477 Dearborn® 1-1/4" 45 Degree Slip Joint Elbow, Chrome - 20 Ga.

Yes. The Dearborn 8477 is a 1-1/4 inch 45 degree elbow with slip joint ends, so it slides over 1-1/4 inch tubular trap tubing and seals with the supplied washers rather than threading or soldering. Slip joint is the standard connection on tubular lavatory and sink drainage, so this drops into an existing 1-1/4 inch tubular assembly without cutting threads.

Everything needed to make both joints ships with it: 2 zinc nuts and 2 rubber washers. Put it in the truck and you can make up both ends of the elbow on the spot with no extra parts.

Gauge is the wall thickness of the brass tube, and lower numbers are thicker. The Dearborn 8477 elbow is 20 gauge brass, which is the heavier of the two common tubular weights and the one specified for commercial and institutional lavatory work; 22 gauge is the lighter residential grade. If a school, hospital, or hotel spec calls out 20 gauge chrome brass tubular, this meets that call-out.

Brass, 20 gauge, with a chrome finish over it. That is a metal tubular fitting, not a chrome-look plastic one, which matters on exposed lavatory work where the trap is visible and on commercial restrooms where plastic tubular gets abused.

Use the 45 when the trap arm has to shift sideways to meet a wall stub that is off center from the sink drain. Two 45s make a gentle offset that drains better and rods out easier than a pair of 90s. Go to a 90 only when you need a hard square turn. The 8477 is the 1-1/4 inch chrome brass 45 for lavatory tubular sizes; a 1-1/2 inch fitting is what you want on a kitchen sink or a tub waste.

Yes, and that is the point of slip joint. The nut and rubber washer compress onto the tube rather than bonding to it, so you can loosen the nuts, rotate or slide the elbow to fine tune the trap arm alignment, and retighten. No solvent weld, no solder, no thread sealant. Hand tight plus a light snug is the usual practice; over-torquing a slip nut rolls the washer.

The 8477 is finished in chrome, the same finish used on standard chrome tubular traps, tailpieces and escutcheons, so it blends on an exposed ADA-style lavatory where the trap is visible under the bowl. If your building standard is brushed nickel or polished brass, this one will not match.

Order it as Oatey Dearborn 8477. That number covers the 1-1/4 inch, 45 degree, 20 gauge chrome brass slip joint elbow with the two nuts and two washers included. Distributors cross-referencing the Dearborn tubular line will find it under that same four digit designation.

0.36 pounds each, at 0.044 cubic feet. Small enough that a case of them adds nothing meaningful to a van stock or a job box, which is why maintenance shops keep them on the shelf by the dozen.
