OATEY 271408 – Frequently Asked Questions
1) Will the Cherne 4 in. Sure-Grip plug fit 4 inch Schedule 40 PVC pipe?
Yes. The Cherne Sure-Grip plug, Oatey 271408, is sized 4 in. (100 mm) nominal and fits both schedule 40 and schedule 80 pipe at nominal sizes. It seats inside the pipe and seals with a natural rubber O-ring against the pipe wall.
2) Can I leave this Cherne plug in the line permanently, or is it test only?
Either. The Sure-Grip plug is made to serve as a permanent or a temporary plug, so you can pressure test with it and then leave it in place as the closure rather than pulling it and fitting a separate cap.
3) Can I turn this 4 inch plug into a cleanout?
Yes. The Sure-Grip body can be tapped for use with a cleanout cover, so a plug left permanently in a 4 inch line can be converted to an accessible cleanout point rather than being cut out later.
4) Do I need a different plug if my 4 inch line is cast iron or Schedule 80 rather than PVC?
Schedule 80 is covered directly, since the plug fits schedule 40 and 80 pipe at nominal sizes. The sizing is by 4 in. (100 mm) nominal pipe, so what matters is that the inside of the pipe is a nominal 4 inch opening for the plug to grip.
5) What is the Cherne Sure-Grip plug made of, and will it hold up in a sewer line?
The body is polypropylene with a natural rubber O-ring seal. Polypropylene stands up to the moisture and normal drain waste conditions in a DWV line, and the yellow body makes an installed plug easy to spot in a trench or riser during walkthrough.
6) Is a 4 inch Sure-Grip plug light enough to set by hand in an overhead or riser location?
It weighs 0.45, so a single tech can carry and set several on a rough-in without handling equipment. The plug goes into the pipe end and is tightened by hand or with a wrench on the nut to expand the seal.
