The application of automobile silicone hose
Silicone rubber has excellent insulation, heat resistance, oil resistance, and aging resistance. It can improve the performance of various parts of the car. Silicone tubes can be used in almost all aspects of the automotive industry. Silicone is used for automotive gaskets and other seals. It can provide strong and lasting sealing protection for all devices from headlights to oil filters, which is leak-proof and durable. In addition, it will not crack or break under extreme temperatures and pressures. Used in connectors, it can protect the electrical connections of automotive connectors, including electrical plugs and sockets, from moisture and corrosion. Used in spark plug protective covers, it can prevent spark plugs from splashing, moisture and dust adhesion. This is essential for the smooth operation of the ignition system.
It also has good electrical insulation properties and heat resistance. Used in radiators, heat exchangers and water pump gaskets. It can ensure that these parts are not corroded during the transmission of antifreeze. It can also be used for cylinder head gaskets, engine covers, valve covers, oil pumps or oil pans to improve their oil resistance.
As life is getting better and better, the use of cars is also increasing. Because cars will release a lot of heat during driving, the requirements for silicone will also be high.
High temperature resistant silicone tube is mainly used in automobiles because of its advantages:

How to distinguish auto silicone hose and rubber car hose
Automotive silicone braided hose has anti-vibration effects such as resistance to fuel, lubricating oil, engine oil, aging resistance, wear resistance, etc. Therefore, it can be used in the hood for many years and remain strong. More importantly, these high-temperature resistant silicone products help reduce the maintenance costs of automobiles and reduce bridge crane failures. This has greatly promoted the development of high-temperature resistant silicone hoses in the automotive industry.
How to distinguish between rubber hoses and silicone hoses
Smell
High-temperature resistant silicone hose products do not volatilize gas so you can’t smell the smell. The double two four vulcanization process will have a slight but not pungent smell. The high-temperature resistant rubber hose will volatilize a pungent smell
Combustion
The smoke of the automotive silicone braided hose is white and non-irritating, and the ash is gray-white solid. Rubber combustion is black smoke with a pungent smell, and the ash is black paste.
Temperature resistance effect
The automotive silicone braided hose can reach a high temperature of 300° and a low temperature of -40°. The high-temperature resistant rubber hose is in the range of 150° low temperature -30°.
Application field
The automotive silicone braided hose has passed food grade certification. And it works in special food and medical high temperature resistant environment. Rubber tubes cannot because plasticizers are added to the product, which is a toxic additive.
Color difference
Silicone can have a variety of colors, and high temperature resistant ones are generally iron red. Rubber is mainly black or brown.
