The Correct Method for Selecting Rubber Seals

The correct methods for selecting rubber seals are as follows:

1. Movement Direction

First, determine the movement direction of the seal's installation position, such as reciprocating, rotational, helical, or fixed.

2. Sealing Focus

For example, confirm whether the moving part is a rod seal on the inner diameter or a piston seal on the outer diameter, etc.

3. Temperature Rating

Refer to the original equipment manufacturer's (OEM) mechanical instructions or evaluate the operating temperature based on the actual working environment to determine the required material. For instructions on temperature ratings, please refer to the production user notes below.

4. Pressure Rating

Consult the relevant data from the OEM mechanical instructions, or infer the working pressure rating by observing the hardness and structure of the original seal. For instructions on pressure ratings, please refer to the production user notes below.

5. Size Measurement

Most users purchase seals based on old samples, but after prolonged use, factors such as temperature, pressure, and wear can significantly affect the original dimensions of the seal. Using samples as a reference is only a starting point. A better approach is to measure the dimensions of the metal groove where the seal is installed, which ensures higher accuracy.
