It’s a full-face gasket made from a Cork and Buna-N (Nitrile) rubber blend, which provides a reliable, low-torque seal against common tank trailer cargoes like crude oil and petroleum products. You’d replace this gasket whenever you service or remove the drain sump assembly to prevent leaks at the flange connection. The 12-hole bolt pattern and specific flange dimensions ensure it fits standard 6-inch TTMA sumps found on many crude, chemical, or pneumatic trailers.
