Products Application O-ring: O-ring means O-shape cross section seals. It can apply to seal all liquid, gaseous media. It excellent performance is also widely used in general pneumatic and hydraulic machinery.
O-ring Information What is an O-ring?
O-ring (O ring, O-ring, Oring, o-rings), is a O-shape cross-section elastomer seal. Different material solve different problems. O-ring is the cost-effective and primarily for sealing.

O-ring sizes:
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.

O-ring material:
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.

O-Ring Applications :
Electronics Industry, Automobile Industry, Machinery Industry, Electric equipment, Medical equipment, Sports Equipment, Household Items and other Industries rubber parts.

O-Ring Characteristics :
  1. Cost-effective
  2. O-ring can be reused
  3. O-rings require very little room
  4. Easy to set-up
  5. Static and Dynamic sealing
  6. It is common sealing solutions
  7. Many sizes available and easy to obtain
  8. One piece groove design reduces hardware and design costs
  9. Compound material choice for different purpose
O-ring selection and design O-rings known as O-rings, Orin, Orings, O shape ring are sealing and preventing unwanted loss. It should be considered a sufficient sealing surface contact pressure, a smaller friction and operating temperature to avoid permanent deformation.

1. Low Friction
The friction coefficient should be low between Oring 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.
2. Recommended O-ring application service temperature
O-ring 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.
3.Comoression 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.

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: CNL CNC department can support rapid processing all kinds of sealing products request. Co-operating with clients to develop new products and improving sealing result.
