There is a little leakage as the fluid vapors get released into the atmosphere from the faces of the seal, though. Since the quantity is hardly quantifiable, the seals are considered leak proof.
Nitrile (also known as Buna N)
Depending on the application, premium lip materials may need to be used, such as Ethylene-acrylic (Varmac®). This material features good abrasion and dry running capabilities, higher heat capabilities than nitrile and polyacrylate, and better low-temperature performance than polyacrylate.

1. The structure of the oil seal is simple and easy to manufacture. Simple oil seals can be molded once. Even the most complex oil seals are not complicated to manufacture. Metal frame oil seals can also be composed of metal and rubber required oil seals only by stamping, bonding, inlaying, molding and other processes.
