O-rings FAQ
What is the purpose of O-ring?
The primary role of O-rings is to prevent the leakage of fluid or air by serving as a sealing mechanism. When compressed between two surfaces, the O-ring eliminates any clearance, effectively preventing the release of fluid or air. Furthermore, O-rings retain their original shape, naturally returning to their initial state once released. This inherent memory feature enables O-rings to establish seals even under minimal or zero pressure. Application of pressure causes the O-ring to compress against the groove wall, resulting in expansion in the opposite direction.
How do I pick the right O-ring?
O-rings are sealing and prevent unwanted loss.It should be considered a sufficient sealing surface contact pressure, a smaller friction and operating temperature to avoid permanent deformation.
The friction coefficient should be low between the O-ring and the device. That can make o-ring life growth and well abrasion resistance. It will still have a good seal damping effect after wearing.
O-ring material may fail due to high temperature or low temperature, chemical corrosion, vibration, wear and movement. At very low temperatures, almost all engineered materials are hardened and can not be sealed; at very high temperatures, the material may burn or decompose. So we should consider those circumstances to select the material.
(1) Hardness : The lower hardness and the bigger compression ; The higher hardness and the smaller compression. The low pressure will use the softener hardness and otherwise the opposite.
(2)Material : The compression set on/about 20% , recommend NBR, EPDM, SILICONE material; The compression set on/about 15%, recommend special FKM, FKM/VITON and PU.
What is the full spectrum of O-ring sizes that are available?
CNL produces different specification o-rings. Sizes illustrate the inner diameter and cross section. O-ring specification of AS586 type, JIS type, P type, G type, S type, AS type, JASO type, Metric type, Bs type and Park type are available. All products are qualified ISO9001: 2008.
Which type of material is utilized in the manufacturing process to make O-rings?
We can produce different kinds of material based on customers' demand, such like NBR, SILICONE, FKM, EPDM, PU, FFKM…… etc. Rubber materials and characteristics please refer to "Rubber Characteristics and Appliocation.
What are the various practical applications and uses of O-Rings in different industries and sectors?
Electronics Industry, Automobile Industry, Machinery Industry, Electric equipment, Medical equipment, Sports Equipment, Household Items and other Industries rubber parts.
What are the various practical applications and uses of O-Rings in different industries and sectors?
What is the process involved in the manufacturing of O-rings?
Some manufacturing companies inject preheated material, such as rubber, into a mold cavity, in order to create O-rings. The mold cavity is then fitted with a plug on top, enabling to pressure the mold cavity. With pressure increasing inside of the mold cavity, the preheated material takes the shape of the mold cavity.
What factors should be considered when choosing the right O-ring size for a specific application?
When customers select O rings, they should consider 3 factors:
Low Friction: The friction coefficient should be low between O rings and the device. That can make o-ring life growth and well abrasion resistance. It will still have a good seal damping effect after wearing.
Recommended O-ring application service temperature:
O-rings material may be failure due to high temperature or low temperature, chemical corrosion, vibration, wear and movement. At very low temperatures, almost all engineered materials are hardened and can not be sealed; at very high temperatures, the material may burn or decompose. So we should consider those circumstances to select the material.
Compression forces and Durability:
(1) Hardness: The lower hardness and the bigger compression; The higher hardness and the smaller compression. The low pressure will use the softer hardness and otherwise the opposite.
(2)Material: The compression set on/about 20%, recommend NBR, EPDM, SILICONE material; The compression set on/about 15%, recommend special FKM, FKM/VITON and PU.
What is the best way to store o-rings to maintain their longevity and performance?
Long-term storage of seals can cause physical changes, including hardening, softening, cracking or decomposition. The factors caused are damage, oxygen, light, ozone, temperature, humidity, oil or solvent.
- Fitting with buffer:
When the suction cups contact to the object, to reduce the force and to compensate the position different between the working objects. - Oil Seal:
Oil seal is also known as metal case and grease seal. To prevent lubricant leakage and to seal other fluids, gases and powdered or granular solids to the machine and vehicle when operation. - Customized Part OEM.ODM:
