OATEY 791A-1 – Frequently Asked Questions

1) Will a 1-1/4 inch extension tube work on a lavatory sink tailpiece drain?
The Dearborn 791A-1 is a 1-1/4 inch extension tube, which is the standard lavatory and bathroom sink drain size. It will not fit a kitchen sink drain, which runs 1-1/2 inch. For a kitchen you need the 1-1/2 inch size tube instead.
2) Does the Oatey 791A-1 extension tube come with the slip joint nut and washer, or do I buy those separately?
The nut and washers come with it. The 791A-1 is supplied with a slip joint nut and washers, so it threads straight onto the existing slip joint connection without buying loose parts.
3) Can I cut this 12 inch extension tube shorter to fit my rough-in?
Yes. The 791A-1 is a 12 inch chrome-plated brass tube with the slip joint at one end, so the plain end can be cut down with a tubing cutter to suit the drop between the trap and the tailpiece. Cut from the plain end only and leave the nut end intact.
4) What does "budget gauge" mean on a brass extension tube, and where should I not use it?
Budget gauge refers to the wall thickness of the brass, which is thinner than standard or heavy gauge tube. The 791A-1 is still chrome-plated brass, so it suits residential and light duty lavatory drain work. For high traffic commercial restrooms or exposed ADA installations where the tube takes knocks, a heavier gauge tube holds up better.
5) Will a chrome extension tube match my existing exposed P-trap under a pedestal sink?
The finish on the 791A-1 is chrome, so it matches standard polished chrome exposed traps and tailpieces. If the trap under the sink is brushed nickel, oil rubbed bronze, or unplated rough brass, the chrome will not match on an exposed installation.
6) Do I need solder, glue, or tape to install the Oatey 791A-1?
None of those. It is a slip joint connection, so it assembles with the nut and washer hand tight plus a light turn with a wrench. No solder, no cement, and no thread sealant on the slip joint washer.
7) What is the part number and weight on the Dearborn 12 inch slip joint extension tube?
Order it as Oatey Dearborn 791A-1. It is a light part at 0.3 lb, so a maintenance tech can stock several on the truck without adding weight.
