PTFE Oil Seals

Product Details

Teflon® PTFE oil seals

Modern diesel and gasoline engines make increasingly high demands on oil seals. This is particularly due to the higher engine speed and oil temperature. In addition, increasingly long maintenance intervals for oil changes are required, which makes the utilized additive-rich oils more aggressive toward the sealing material. Oil seals made from fluoro rubber (FKM), which are often used, can only fulfill these increased demands to a limited extent. 


Material range: all materials come from world famous brands like Dupont, Daikin, 3M, 3F, Dongyue, etc.
