The Purpose of O-ring:

(1) O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements.

(2) O-ring may be used in static appliC.A.Tions or in dynamic appliC.A.Tions where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.

(3) O-ring usually using for static seal (eg: water/ oil/ gas/ chemical solvents /chemical medicine)liquid environment etc. Sometimes can be use for semiconductor vacuum environment.

Feature:

Wear-resistant, impact-resistant, heat-resistant, cold-resistant, uv-resistant, oil-resistant, corrosion-resistant, oxidation-resistant, anti-slip, resilience, shoock-proofing, anti-static, noise-absorbting, durabe, non-toxic, long lifes pan.

O-ring Applicable Scope:
Various types of seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters element.

O-ring Installation Requirements:

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

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

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

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

4. Do not use grease containing solid additives, such as molybdenum disulfide and zinc sulfide.

• Manual installation of O-ring (O-shaped rubber sealing ring):

1. Use tools without sharp edges;
2. Ensure that the O-ring (O-shaped rubber seal ring) is not twisted, and the O-ring (O-shaped rubber seal ring) shall not be stretched excessively;
3. Try to use auxiliary tools to install O-rings (O-shaped rubber seals) and ensure correct positioning;
4. For the O-ring (O-shaped rubber sealing ring) bonded with a sealing strip, it must not be stretched at the joint.
