OATEY 765-1 – Frequently Asked Questions

1) What size bathtub overflow does the Oatey Dearborn 765-1 plug fit?
The Dearborn 765-1 is a 1-1/4 inch overflow plug with a 12 inch tube, so it suits standard 1-1/4 inch tub waste and overflow piping. The 12 inch dimension is the tube length reaching down from the overflow opening, not the plug diameter.
2) Which length Dearborn overflow plug should I order for my tub test?
The patent overflow plug is made in 5, 6, 8 and 12 inch lengths; model 765-1 is the 12 inch. Pick the length that puts the sloped gasket at the overflow while the tube still clears the waste tee below. Short shoe-fit tubs usually take the 5 or 6 inch; deeper roughs are where the 12 inch earns its place.
3) Will a Dearborn overflow plug hold water pressure for a plumbing rough-in test?
That is what it is built for. The 765-1 is a two piece assembly that draws a sloped gasket tight against the overflow opening to seal the waste and overflow line so the system can be filled and inspected, then backed off and pulled out without cutting anything.
4) Is the Oatey 765-1 a permanent overflow fitting or a temporary test part?
It is a test plug, not a finish trim part. The 765-1 goes in to seal the overflow while the waste line is water tested, and comes back out before the tub waste and overflow face plate is installed. If you need the finished overflow cover and linkage, that is a separate waste and overflow trim kit.
5) Why does the Oatey 765-1 use a sloped gasket instead of a flat one?
Tub overflow openings sit on the slanted face of the tub, not square to the tube. The sloped gasket on the 765-1 matches that angle so the seal seats flat against the overflow face rather than pinching on one edge and weeping during the test.
6) Is the Dearborn 765-1 overflow plug brass or plastic?
Brass, 20 gauge, with a chrome finish. Brass tube takes repeated tightening on job after job better than a molded plastic test plug, which is why the Dearborn pieces get reused across a whole rough-in run.
7) How is the Oatey 765-1 packed, and how heavy is it to ship or carry?
Individually boxed as a two piece assembly, weighing 0.8. It is a single plug per box, so order one per opening you plan to test at the same time.
8) What is the manufacturer part number for the 12 inch Dearborn patent overflow plug?
Oatey Dearborn 765-1. That number covers the 1-1/4 inch by 12 inch chrome brass patent overflow plug; the shorter 5, 6 and 8 inch versions carry their own part numbers in the same family.
