What Is The Function Of The Rubber Dust Cap

The main function of the rubber dust cap is to prevent dust and leakage. It is to prevent sand and rain from entering the discharge hole, preventing the hole that needs to be protected or clogging, rust and other problems. Rubber dust caps can be made of nitrile, fluorine rubber, silica gel, etc. (or other rubber materials). Rubber dust caps are widely used in automobiles, machinery, valves and other industries.

The rubber dust cap is made of different types of rubber, which can meet the temperature working environment area of -50℃-+200℃. The rubber dust cap has good abrasion resistance, oil stain resistance and aging resistance. It can be designed according to requirements.

For example, the rubber cap on the automobile brake cylinder is the rubber dust cap of the exhaust valve. Whenever you change the brake fluid or drain the brake system, you must first unplug the dust cap, and then loosen it in the counter [clock] direction. If the exhaust valve is drained and drained, if the dust cap is lost, the actual impact will not be significant. Even if it is lost, the exhaust valve will be released and the brake fluid will be able to flush out the clogged mud and sand, and the old vehicle will be lost. There are many cases, and generally they are not available for purchase separately. If they are lost, they can be disassembled and installed after replacing the old parts. If it is not installed, it will have little effect.
