OATEY 271308 – Frequently Asked Questions
1) Will the Cherne 3 inch Sure-Grip plug fit schedule 80 pipe, or only schedule 40?
Both. The Sure-Grip plug seats in 3 inch nominal pipe and the description states it fits schedule 40 and schedule 80 at nominal sizes. Nominal is the key word: schedule 80 has a thicker wall and a smaller inside diameter than schedule 40, and the plug's rubber O-ring expands to take up that difference. Size it by the nominal pipe call-out, 3 inch (75 mm), not by a measured ID.
2) Can a Cherne Sure-Grip plug be left in the pipe permanently, or does it have to come out after the test?
It can stay. The Sure-Grip is rated for permanent or temporary use, so it works as a dead-end cap on an abandoned 3 inch branch as well as a test plug you pull after the inspection. That is the practical difference from a pure test-only plug: property managers capping off a line during a remodel can leave this one in place.
3) What is the Cherne 271308 Sure-Grip plug made of, and will it hold up in a DWV line?
Polypropylene body with a natural rubber O-ring seal. Polypropylene handles the chemistry in a drain, waste and vent line and will not corrode the way a metal mechanical plug can when it sits in a wet pipe for months. The rubber O-ring is the wear item: it is what grips the pipe wall and makes the seal, so a nicked or dried out ring is the usual reason a plug starts weeping.
4) How do I identify a Cherne Sure-Grip plug on the jobsite once it's installed?
By color and size. The Sure-Grip is yellow, and the 3 inch is the 271308. If you are standing at an open riser trying to work out what somebody left in the line before you got there, the yellow polypropylene head is the tell.
5) How many 3 inch Sure-Grip plugs can I carry for a multi-unit rough-in?
Each 3 inch Sure-Grip weighs 0.3 and takes 0.013 in volume, so a full set for a stack of units is a bucket, not a load. Plumbers testing multi-family risers typically pull one per fixture branch plus spares, since the O-ring is the part that gets damaged going in past a burr.
