OATEY 270270 – Frequently Asked Questions
1) Does the Cherne 270270 go inside the pipe or on the end of it?
It is an end-of-pipe plug. The plug installs in the open end of an 8 inch line and the rubber O-ring expands against the inside wall as the nut is tightened, so it is for testing or sealing an exposed pipe end, not for mid-run or through-a-cleanout work.
2) Do I need a wrench to tighten this test plug?
No. The 270270 uses an extra large zinc wing nut you tighten by hand, so no wrench is required in the trench or at the stack. The carriage bolt behind it is zinc-plated to resist rust and corrosion through repeated wet use.
3) What is the Cherne Gripper plug made of, and will it hold up to repeated job-site reuse?
The compression plates are ABS glass-reinforced for added strength, the seal is natural rubber chosen for expansion and memory, and the bolt and wing nut are zinc-plated hardware. The rubber's memory is what lets it be pulled, stored, and reset on the next opening without taking a permanent set.
4) Is the Cherne 270270 the yellow plug my crew is already using on other sizes?
Yes, the 270270 carries the yellow Cherne Gripper finish, the same visual family as the other Gripper sizes, which makes it easy to spot in a pipe end before backfill. For a facility standardizing on one plug family, it keeps the 8 inch openings consistent with the smaller ones.
