The correct ways to choose rubber seals are:
1. Direction of movement - determine the direction of movement of the sealing element in the position, such as reciprocating, rotating, spiraling or fixing.
2. Key sealing points - for example, tie rod seals that determine the point of action is inside diameter or piston seals that determine the point of action is outside diameter.
3. Temperature grade - determine the required materials by referring to the original instructions or evaluating the working temperature according to the actual working environment.Please refer to the following notes for production users for instructions on temperature levels.
4. Pressure level - refer to the relevant data from the original factory machinery instructions, or infer the working pressure level by observing the hardness and structure of the original seals. Please refer to the following notes for production users.
5. Size - most users will be used by the old sample of choose and buy, but the seal in use after a period of time, will be affected by factors such as temperature, pressure and wear greatly its original size, choose according to the samples can only be as a reference, a better approach is to measure metal seal position groove size, higher accuracy.
