Finished oil seal are installed in metal housing and directly rubber – PTFE vulcanization with metal housing two kinds of methods. The traditional oil seals are always installed directly in engine cast iron housing body, due to inconvenience installation and removing, very easy to damage the housing shape deformation, happen oil leakage possible. This kind of oil seal using avoid this issue happen, according to the design of location holes of the installation metal housing, directly install the oil seal on the engine body with screw, very convenient to install and remove. The international OEMs are using this new type of structure oil seals.

Because of aluminum material has low density, high intensity, and good plastic and corrosion resistance of the particularity of ability, according to the engine structure characteristics, some engine need to be installed to use aluminum material housing. Same theory as iron housing oil seal, according to the design of location holes of the installation metal housing, directly install the oil seal on the engine body with screw, very convenient to install and remove. International many OE manufacturers are using this new type of structure oil seals.

PPS, is a new type of high performance thermoplastic resin, with high mechanical strength, high temperature resistance, resistance to chemicals, difficult to burn, thermal stability, excellent electrical performance advantages, it can also be used in material selection for housing oil seals.

The biggest characteristic of this kind oil seal has the corresponding wear ring (collar) besides oil seal itself. There are two types, with flanges and no flanges. The wear sleeves main function is to replace the crankshaft wear face, avoid axis surface wear or damage, installation is convenient, economical and practical. Foreign vehicles are widely used of this wearing, such as Caterpillar, Detroit, John Deere, Cummins, etc.
