OATEY P9793E – Frequently Asked Questions

1) Will the Oatey P9793E extension tube connect to standard 1-1/2 inch kitchen drain piping?
Both ends of the P9793E Dearborn extension tube are 1-1/2 inch slip joint, so it mates with the 1-1/2 inch slip joint tubular drain piping used under a kitchen sink. Slip joint means the washer and nut do the sealing, so nothing is glued or threaded into the tube itself. It ships with one slip joint washer, one washer, and one reducing washer.
2) Can the P9793E 16 inch extension tube be cut down to fit a shorter drop?
Yes, the tube is made to be cut to length. It's polypropylene, so a tubing cutter or fine tooth saw handles it, and because both ends are slip joint you only need one cut end to sit inside a slip nut and washer. Cutting from the 16 inch length is the usual way to hit an odd dimension without ordering a different part.
3) Does the Oatey P9793E meet plumbing code for tubular drain fittings?
The P9793E is IAPMO listed and meets ASTM F 409, the standard covering thermoplastic tubular drain fittings. Those two are what an inspector or a spec writer on an institutional job looks for on a plastic tubular waste part.
4) What is a double connect extension tube used for on a garbage disposal install?
A double connect tube is the piece you use when a disposal install leaves you with two tailpieces feeding one trap. Having slip joint on both ends, rather than a flanged or flared end, lets it pick up a connection at each end instead of dead-ending at a fixture. Oatey lists disposal applications where two tailpieces are needed as the intended use for the P9793E.
5) Do I need a wrench or pipe dope to seal the P9793E slip joint connections?
No. The washer seals the joint with hand tightening, and the blue TPE washers resist drying out and cracking over time. Overtightening plastic slip nuts with a wrench is how they crack, so hand tight plus a light snug is the right approach.
6) What other lengths does the Dearborn double connect slip joint extension tube come in?
The double connect slip joint extension tube is made in 6, 8, 12, and 16 inch lengths. The P9793E is the 16 inch. If the sink drop is short, start from a shorter length rather than cutting a lot of waste off the 16.
7) Can I use the P9793E to join two different tubular sizes?
A reducing washer is supplied with the tube, which is what lets a 1-1/2 inch slip joint end take a smaller tubular pipe, typically 1-1/4 inch, inside the same nut. The tube body itself is 1-1/2 inch at both ends, so any reduction happens at the washer, not in the tube.
8) Is the Oatey P9793E extension tube white or chrome, and does it matter under an exposed sink?
It's white polypropylene. The double connect tube is also produced in black polypropylene. For an exposed application, such as a wall hung lavatory in a lobby or an ADA sink where the trap is visible, plastic in white or black is a finish decision, and a chrome tubular part is what most specs call for there instead. Under a cabinet it makes no difference.
9) Will polypropylene hold up to hot water and drain cleaner in a commercial kitchen?
Polypropylene is the material used here, and it's the standard thermoplastic for tubular waste because it takes hot water and caustic drain chemicals better than the PVC or ABS used on the DWV side. The part also meets ASTM F 409 for thermoplastic tubular drain fittings. What it is not is a substitute for a metal tube where a job spec calls out brass.
10) How much does the Oatey P9793E extension tube weigh for a stock order?
Each P9793E tube weighs 0.32 and carries a volume of 0.059, so a case of them is light and takes little shelf space. For an MRO crib stocking multiple sink configurations, the 6, 8, 12, and 16 inch lengths of this tube are the set that covers most drops.
