Automotive Gaskets and Seals
Automotive gaskets refers to a mechanical seal which is used for filling the gap between the two components in order to ensure that there is no leakage between them during compression stage. These are manufactured using variety of materials like gasket paper, plastic polymer, rubber, fiberglass, silicone, metal, cork, and felt. Gaskets can bear both low and high compressive loads. Automotive gaskets come in different designs, shape and specifications. Commonly used gaskets include sheet, solid material, spiral wound, and double jacketed. Automotive seals are the stationery sprung elements that are used for holding tightly the various components of an automobile. Seals are mostly made of rubber or stainless steel. The different types of seals widely used today in automobiles are camshaft and auxiliary shaft seals, water pump seals, trans axle seals, oil seals, wheel bearing and axle grease.

Types of Automotive gaskets and Seals 

Automobile Cooling System Gaskets Differential Gaskets and Seals Engine Gaskets and Seals
Fuel System Supply Gaskets Transmission Gaskets and Seals

Differential Gaskets and Seals are specifically designed to prevent dirt and grime from getting into the axle tube and damaging the crucial components of automobile transmission components. Differential gaskets and seals are usually flexible seals that are affixed on the axle used in transmission. Also, these gaskets and seals hold the gear oil in and throw the left out impurities out. Axle seal is one of the important types of differential gaskets and seals.

Automobile Cooling System Gaskets
Automobile Cooling System Gaskets are used for sealing or fixing together the matched components and pipe joints so that the gas or liquid does not leak. Soft sheet metals are used for producing automobile cooling system gaskets. The other material that can be used for making gaskets are bullet steel, stainless steel, graphite, silicon, neoprene, polymeric resins, copper, nitriles and fibre-based composites. These gaskets are installed in automobiles so as to ensure that the fluids or gases do not leak out. Cooling system gaskets seals act as a powerful barrier among the cylinder head and block of any engine.

Engine Gaskets and Seals makes sure that the oil, fluids, coolant and air do not leak out from internal and outside passages of an internal combustion engine. These gaskets tightly seal the cylinders so that maximum compression takes place in the engine cylinder. Head gasket is the most critical gasket used in the automobile engine system that absorbs all the heat and compression produced by the engine of the vehicle.
Other important engine gaskets and seals are:

Fuel System Supply Gaskets
Fuel System Supply Gaskets are mostly used for obstructing the leakage of fluids thereby maintaining the appropriate pressure in an engine enclosure. It acts as a strong seal between two static surfaces. Fuel pump gaskets consists of a flexible material, which is put between the fuel pump spacer block and fuel pump-mounting surface in order to check oil leakage.

Transmission Gaskets and Seals are made of flexile material generally in the form of a ring or sheet that are used for making a pressure-tight connection between the automobile transmission components. Transmission gaskets and seals are of two types: internal seals and external seals. Internal seals are installed in vehicles to obstruct the leakage in accumulators, servos and clutch packs while external seals are used for stopping the leakage of fluid taking place outside the trans axle case.
