OATEY 270245 – Frequently Asked Questions
1) What pipe size does the Cherne 270245 End of Pipe Gripper Plug fit?
The Cherne 270245 Gripper Plug is a 4 in. (100 mm) nominal size plug. It seals on the end of a 4 inch pipe, not inside a run, so the pipe end has to be accessible and reasonably clean for the rubber O-ring to seat.
2) Do I need a wrench to tighten the Cherne 270245 test plug?
No. It uses an extra large zinc wing nut, so it hand tightens. Handy when you are working a trench or a crawlspace and do not want to carry tools to every riser.
3) What is an end of pipe plug and when would I use one instead of an inside-the-pipe test plug?
An end of pipe plug like the Cherne 270245 clamps over the open end of a 4 inch pipe rather than expanding inside the bore. Use it when the pipe end is cut off and exposed, such as a stub-out, a stack top, or a line end during rough-in. If you need to block a line partway along its run or seal inside a cleanout or hub, you want a mechanical or pneumatic plug that expands inside the pipe instead.
4) Is the Cherne 270245 plug reusable, and will it rust after sitting in a wet trench?
It is built for repeat use. The carriage bolt is zinc plated to resist rust and corrosion, the wing nut is zinc, and the sealing element is natural rubber chosen for expansion and memory so it returns to shape between uses. The compression plates are ABS glass-reinforced for strength.
5) How heavy is the 4 inch Cherne Gripper Plug for stocking a service truck?
Half a pound each, 0.013 volume, so a plumber or MRO crew can carry several sizes on a truck without taking up a bin. The yellow body makes it easy to spot in a trench or an open ceiling so it does not get left in the line.
