This is a 10‑foot length of Buna‑N (nitrile) o‑ring cord, typically used as a manlid gasket to seal manhole covers on tank trailers, isotanks, or bulk storage tanks.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
Buna‑N provides good resistance to petroleum‑based fuels and oils, and the cord can be cut and spliced to fit the exact circumference of a manlid groove. It forms a reliable, leak‑proof seal when the lid is clamped down.
