Installation Requirements for O-ring Seals

1. Requirements for installing O-rings

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

1. Whether the lead-in angle is processed according to the drawing and whether the sharp edge is chamfered or rounded;

2. Whether the inner diameter is deburred and whether the surface is contaminated;

3. Whether the seals and parts have been coated with grease or lubricating liquid (to ensure the media compatibility of the elastomer, it is recommended to use the sealed liquid for lubrication);

4. Grease containing solid additives, such as molybdenum disulfide and zinc sulfide, must not be used.

2. Manually install the O-ring

1. Use tools without sharp edges;

2. Ensure that the O-ring (O-type rubber sealing ring) is not twisted, and the O-ring (O-type rubber sealing ring) must not be stretched excessively;

3. Try to use auxiliary tools to install the O-ring (O-type rubber seal) and ensure correct positioning;

4. For O-rings (O-type rubber sealing rings) bonded with sealing strips, they must not be stretched at the connection.

3. Installation screws, splines, etc.

1. When the O-ring (O-type rubber sealing ring) is stretched and needs to pass through screws, splines, keyways, etc., an installation mandrel must be used. The mandrel can be made of softer, smooth metal or plastic and must not have burrs or sharp edges.

2. When installing the compression screws, tighten the screws symmetrically and not in sequence.
