O-ring rubber seals are widely used in internal combustion locomotives, automobiles, tractors, construction machinery, machine tools, and various hydraulic and pneumatic components, such as seals, which may have fixed, reciprocating, and rotary motion seals. Rubber O-ring seals account for more than 50% of mechanical products. We need to produce sealing components that are suitable for various special rubber sealing products, high temperature, low temperature vacuum, high pressure, and different media.

Firstly, the requirements for installing O-rings (O-ring rubber seals)

When installing the O-ring (O-ring rubber seal), check the following:

The introduction corner is processed by chamfering or rounding sharp edges in the drawing;

Whether the deburring of the inner diameter surface is contaminated;

Three seals and components have been coated with oil or lubricant (to ensure compatibility with the elastomer medium, it is recommended to use liquid to lubricate the seals);

4. Solid additives such as molybdenum disulfide and zinc sulfide grease may not necessarily be used.

The tool used does not have sharp edges;

2. Ensure that the O-ring (O-ring rubber seal) is not twisted or excessively stretched;

3. Use auxiliary tools to install O-rings (O-ring rubber seals) and ensure correct positioning;

4. Used for bonding sealing strips to prevent the O-ring (O-ring rubber seal) from being stretched during connection.

When the O-ring (O-ring rubber seal) passes through the tension screw, splines, keyways, etc., installation spindles must be used. The mandrel can be made of relatively soft, smooth metal or plastic, without burrs or sharp edges.

2. Install the pressure screws and tighten them in a direction that does not follow the tightening sequence.
