OATEY 273318 – Frequently Asked Questions
1) Can the Cherne Econ-O-Grip 1-1/2 inch plug be used for a pressure test?
No. The Econ-O-Grip plug is not recommended for pressure tests. It is rated for 2 psi (0,14 bar) of back pressure, equal to a 5 ft. (1.4 M) head of water, so it suits low-head DWV water tests and temporary closures only. If you need to hold system pressure, use a plug rated for that duty instead.
2) Will the Cherne Econ-O-Grip plug hold up in drain lines with cleaning chemicals or solvents?
The sealing element is chemical-resistant nitrile rubber and the hardware is stainless steel, so it stands up better than plain steel hardware in wet DWV work and around drain chemicals. The stainless hardware also keeps the wing nut and plate from seizing with rust between uses.
3) How does a mechanical Econ-O-Grip plug compare to an inflatable test ball for a 1-1/2 inch line?
The Econ-O-Grip is a mechanical plug: you set it in the pipe and tighten the nut so the nitrile element expands against the wall, with no air source needed on the job. An inflatable test ball needs a pump and a gauge but can be passed further into a line through a small access point. For a short stub, trap arm or cleanout at 1-1/2 inch, the mechanical plug is the simpler choice, as long as you stay within the 2 psi / 5 ft. head limit.
4) What part number do I order for the 1-1/2 inch Cherne stainless Econ-O-Grip plug?
Order Oatey part number 273318. That is the single model for the 1-1/2 in. (40 mm) stainless steel Econ-O-Grip plug; other sizes carry different numbers.
5) Is the Oatey 273318 plug reusable on multiple jobs?
Yes, it is a mechanical plug built for repeat use: the nitrile element and stainless hardware are meant to be tightened, released and pulled back out. At 0.15 lb it is light enough to keep several sizes in the truck for punch-list work across a building.
