- In addition to their durability, national skeleton TC oil seals are also easy to install and maintain. They are typically designed to be a direct replacement for existing seals, making it quick and convenient to install them in place of worn-out or damaged seals. Once installed, these seals require minimal maintenance to ensure their continued performance.

Selecting Quality Silicone and Rubber Gaskets
Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.

ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).
Proper care and maintenance of square rubber gaskets are essential to ensure their longevity and effectiveness. Regular inspection for signs of wear, damage, or degradation is important to prevent leaks and maintain the integrity of the seal. Replacing worn or damaged gaskets promptly can help prevent costly repairs and downtime.
However, when you actually select the oil seal to use, the most important factors are past success history and points of improvement, so it is not necessary to follow this order to the letter.



EPDM oil seals are less common. They are used in solvent, hot water and steam applications, EPDM resists low temperatures down to -50 °C and UV radiation well. Some types of EPDM are also suitable for higher temperatures up to +150 °C. EPDM oil seals are usually available upon request.
