  • The 20mm thickness provides an excellent balance for many applications; it is thick enough to withstand moderate pressures without being so bulky that it interferes with the assembly of parts. In automotive applications, these gaskets may be found between engine components, ensuring oils and coolants remain where they should, protecting against leakage and subsequent damage.

  • Oil or other seals can be used for grease and oil seals. A flexible lip, radial lip, or rotating shaft seal are different names for an oil seal. Single lip, double lip, triple lip, and four or more lips are frequent configurations. Double dust lip seal A seal with a garter spring design is the Double Dust Lip (DDL) seal. It has two dust lips, as the name would imply, plus a fluid lip with a garter spring to keep the lip firmly attached to the wear ring. Given the ongoing evolution of bearing seal designs, this seal would be considered a starting seal. For more than 50 years, this design has been the workhorse of the freight business; it still is in some regions. NBC Brenco Bearing Seal performs the fundamental task of keeping contaminants and grease out. Because of the garter spring, this seal would add the most torque and temperature to the bearing. Efficiency plus bearing seals Due to eliminating the fluid lip using poly inserts and rotors, the Efficiency Plus (EP) seal has a reduced torque value of fewer than 15 in-lbs. Although it features a triple dust lip rather than a double dust lip, the dust lip is still a molded component of the design. A labyrinth-like insert and rotor interlock each other to replace the fluid lip. NBC Brenco labyrinth provides excellent grease while lowering the torque required to rotate the seal. Other types of oil seal and grease seals include:

  • Typically used in hydraulic high-stress applications where compounds under high pressure are exposed to wear, the benefits of polyurethane seals include:

Their flexibility, durability, and reliability make them an essential component for ensuring leak-free and efficient operations. By choosing high-quality square rubber gaskets and following proper maintenance practices, users can enjoy long-lasting and effective sealing solutions for their applications.


  • The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
