How to purchase maintenance seals?

<p>When purchasing maintenance seals, most users will purchase according to the size and color of the samples, which will only increase the difficulty of purchasing and may not be able to select suitable products. The following procedures are recommended to improve the accuracy of purchasing seals:</p><p><br></p><p>1.Direction of motion; First determine the direction of motion of the seal location, such as reciprocating, rotating, spiral or fixed.&nbsp;</p><p><br></p><p>2.Sealing focus; For example, it is determined that the active point is the pull rod seal in the inner diameter or the active point is the<a href="https://www.dshseals.com/product-category/piston-seal" rel="noopener noreferrer" target="_blank"> piston seal</a> in the outer diameter, etc.&nbsp;</p><p><br></p><p>3.Temperature grade; Refer to the operating instructions of the original machinery or evaluate the working temperature according to the actual working environment to determine the required materials. For the description of temperature grade, please refer to the following precautions for production users.&nbsp;</p><p><br></p><p>4.Pressure rating; Refer to relevant data from the instructions of the original machinery, or infer the working pressure grade by observing the hardness and structure of the original seal. The instructions of the pressure grade can refer to the following matters needing attention for production users.&nbsp;</p><p><br></p><p>5. Size; Most users will choose according to the used old samples, but after using the seal for a period of time, its original size will be greatly affected by factors such as temperature, pressure and wear, 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, which will have higher accuracy.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p>
