Sioux Chief 24030 Double Flanged Tailpiece, Chrome 20GA

The Sioux Chief 24030 Double Flanged Tailpiece is a rough-in waste connector that drops down from the fixture outlet to the trap below, available in sizes ranging from 1/2" x 16" to 1-1/2" x 16" to match the drain connection on the job. Built from 20GA (20-gauge) tubing with a chrome finish, every size in this family shares the same double-flanged design, giving installers a finished look at the fixture outlet while providing a durable slip-joint connection point into the P-trap or waste arm. It is a standard trade item for plumbers working behind the wall or under the fixture on residential and light commercial drain lines, and stocking both the 1/2" x 16" and 1-1/2" x 16" sizes covers the vast majority of lavatory and sink rough-in calls.

Key Features

  • Trade Size Range: available from 1/2" x 16" up to 1-1/2" x 16", sized for standard lavatory and sink drain outlets connecting to a P-trap or waste arm.
  • Durable Construction: fabricated from 20GA tubing for a rough-in-grade drain connector that holds up to routine slip-joint installation and removal across every size in the range.
  • Double Flanged Design: flanges at both ends provide a clean seat for slip-joint nuts and washers at the fixture outlet and trap connection, regardless of which size is selected.
  • Finish: chrome-plated exterior for a presentable appearance at any exposed section of the drain assembly.
  • Consistent Fit and Finish: both the 1/2" x 16" and 1-1/2" x 16" options share the same 20GA chrome double-flanged construction, so contractors can standardize on the 24030 line across multiple fixture types.

Sioux Chief 240-416216C25 – Frequently Asked Questions

1) What does double flanged mean on a tailpiece, and do I need slip joint nuts and washers?
Double flanged means there is a flange formed at both ends of the tube, giving a seat for a slip-joint nut and washer at the fixture outlet and again at the trap or waste arm connection. The nuts and washers themselves are not part of the tailpiece, so order them separately or reuse what is on the existing assembly.
2) Is the Sioux Chief 24030 tailpiece brass or plated steel?
Brass tubing with a chrome-plated finish, in 20 gauge wall. That matters on a repair call: brass won't rust out the way thin plated steel tailpieces do under a lavatory, and the chrome plating is presentable on any exposed section of an under-sink drain assembly.
3) Will a 16 inch tailpiece work if my trap sits only a few inches below the sink?
Yes. The 16 inch length on the 24030 is intentionally long so the installer cuts it down to the drop between the fixture outlet and the trap inlet. Cut from the end that goes into the trap and keep the flanged fixture end intact, since that flange is what the slip-joint nut seats against.
4) I manage apartments and keep replacing corroded sink tailpieces. Can I standardize on one part?
That is the practical case for the 24030 line. Both the 1/2 x 16 inch and 1-1/2 x 16 inch share the same 20 gauge brass, chrome-plated, double-flanged construction, so one line covers lavatory and kitchen sink outlets across a portfolio and the fittings behave the same way at every unit. Stock the 1-1/2 inch for sinks and lavs and the 1/2 inch for the smaller outlets.
5) Is this a trap or a trap arm?
Neither. The 24030 is a tailpiece, the straight tube that drops from the fixture drain outlet down to the trap. You still need the P-trap itself, and the trap arm that carries waste back to the wall. Buy the tailpiece size to match the fixture outlet, then match the trap to it.
