How To Choose The Sealing Ring Correctly

Precautions for maintenance users When purchasing maintenance seals, most users will buy according to the size and color of the sample, which will only increase the difficulty of purchasing, and may not be able to select the right product. The following procedures are recommended to improve the accuracy of purchasing seals:

1. The movement direction-first determines the movement direction of the position of the seal, such as reciprocating, rotating, spiral or fixed.

2. The key points of sealing-for example, determine whether the active point is the tie rod seal on the inner diameter or the active point is the piston seal on the outer diameter, etc.

3. The temperature grade-is consulted from the original machine's operating instructions or evaluates the working temperature according to the actual working environment to determine the required materials. A description of temperature ratings can be found in the Production User Notes below.

4. Pressure level-Check the relevant data from the original mechanical operating instructions, or infer the working pressure level by observing the hardness and structure of the original seal. For the description of the pressure level, please refer to the following precautions for production users.

5. Size-Most users will choose the old samples that have been used, but the original size of the seal will be greatly affected by factors such as temperature, pressure and wear after a period of use, so the sample selection can only be used as a reference , a better method is to measure the size of the metal groove where the seal is located, and the accuracy will be higher.
