O-ring Fluoro Up S (low adhesion + low friction + low sticking + low outgassing)

Fluoroelastomer (FKM) material with low adhesion, low friction, low sticking, and low outgassing properties due to the O-ring cherry seal.

This material is made of fluororubber (type 2) that reduces phenomena such as stickiness (tackiness), adhesion, and gas release, which are characteristics of rubber materials. It has performance levels for heat resistance and chemical resistance comparable to general-purpose FKM. Sakura Seal Co., Ltd. offers a wide range of O-rings, from very small O-rings to large diameter rings, in various sizes and specifications according to JIS standards, and supports the appropriate selection of O-rings in terms of both material and size. * The fluororubber series, including the Fluoro-Up series, is the material that Sakura Seal Co., Ltd. specializes in the most. * We also accommodate shapes other than O-rings.

O-ring Fluoro Up V (Low Adhesion + Low Friction + High Vacuum Resistance)

Low adhesion and low outgassing fluororubber (FKM) material with O-ring cherry seal.

This material is a type of fluororubber (type 3) that has been designed to reduce phenomena such as the stickiness and adhesion characteristic of rubber materials, as well as gas release, to a certain extent while providing high vacuum resistance. It also possesses excellent heat resistance and chemical resistance, including resistance to strong acids and steam. Sakura Seal Co., Ltd. offers a wide range of O-rings, from very small O-rings to large diameter rings, in various sizes beyond the standard sizes specified by JIS standards, and we support the appropriate selection of O-rings in terms of both material and size. * Various types of fluororubber, including the Fluoro-Up series, are the materials that Sakura Seal Co., Ltd. specializes in the most. * We also accommodate shapes other than O-rings.

O-ring NBR-70-2 (Type 2 / Nitrile Rubber)

The O-ring cherry seal is molded from various materials including NBR-70-2 (type 2 / nitrile rubber) and is available in a wide range of sizes.

Among the materials made of nitrile rubber, acrylonitrile is highly contained, and due to its excellent oil resistance, it can also be used for fuel oils. However, it is inferior in weather resistance. Before JIS B2401:2012 established NBR-70-2, it was referred to as Type 2 (old JIS standard = JIS B2401:2005). Sakura Seal Co., Ltd. offers a wide range of O-rings, from very small O-rings to large diameter rings, not only in general standard sizes according to JIS standards but also supports the appropriate selection of O-rings in terms of both material and size. * We also accommodate shapes other than O-rings.

Protect against corrosion from red rust! Water quality improvement equipment for red rust and red water.

If you're troubled by red rust or red water in your cooling water, it demonstrates effectiveness beyond that of chemicals.

【For those troubled by red water in cooling systems】 Chillers, cooling towers, piping, heat exchangers… We will improve your red, murky cooling water and circulation water to be clear! 【We can solve all these concerns!】 ✓ Cooling water and circulation water have turned bright red ✓ Even after replacing the water, it quickly turns bright red again ✓ Red rust is occurring in the distribution pipes and heat exchangers ✓ The frequency of cleaning and maintenance is high, and you want to reduce effort and labor ✓ You want to improve rust issues and minimize damage to equipment By the way, these concerns are very common, as we have conducted over 100 cases of red rust and red water countermeasures over nearly 20 years. Red rust occurs in inconspicuous places within the piping, so it's easy to postpone countermeasures. However, during that time, the piping continues to weaken due to red rust. By the time you notice it, there may be holes causing water leaks, or the piping itself may break, leading to emergency repairs and the urgent shutdown of production lines, posing significant risks.

O-ring "Material Properties and Applications"

[Sample available] This explains the material properties and applications of O-rings made from natural rubber and synthetic natural rubber.

The resistances in the table are primarily characteristics due to the polymer and may vary depending on the formulation. Please confirm through actual machine tests before use. 【Types of Rubber and Their Characteristics】 ■ Natural Rubber: Has elasticity and good mechanical properties such as abrasion resistance. ■ Synthetic Natural Rubber: Almost the same properties as natural rubber. ■ Styrene Rubber: Good abrasion resistance and aging resistance, and is inexpensive. ■ Butadiene Rubber: Has good elasticity and excellent abrasion resistance. ■ Chloroprene Rubber: Has average properties such as weather resistance, ozone resistance, heat resistance, and chemical resistance. ■ Butyl Rubber: Has good weather resistance, ozone resistance, and gas permeability, and is resistant to polar solvents. *Samples are available upon request. If you would like a sample, please apply through [Contact Us]. *Product documentation can be viewed from [Download].

O-ring "Groove Design"

Explaining the use of Tsubushi Shiro, gaps, and backup rings is possible with sample provision.

■Tsubushi Shiro When using O-rings for motion, Tsubushi Shiro significantly affects sealing effectiveness, dynamic resistance, and compression set, so it must be kept to a minimum. In cases of high speed or poor lubrication conditions, please make Tsubushi Shiro even smaller than standard motion O-rings. ■Gap At high pressure, gaps between the piston and cylinder, as well as between the rod and sleeve, can cause extrusion, leading to damage. This gap should be designed to be as small as possible. The use of backup rings is effective in preventing extrusion. ■Use of Backup Rings When pressure is applied from both sides, install backup rings on both sides of the O-ring. When pressure is applied from one direction, install one backup ring on the side opposite the pressure. If there is enough space, it is recommended to use two backup rings even for unidirectional pressure. *Samples are available upon request. If you would like a sample, please apply through the [Contact Us] section. *Product documentation can be viewed from the [Download] section.

[Explanation] Examples of O-ring malfunctions and their countermeasures

Possible sample provided: Explaining examples of O-ring defects and their countermeasures.

Name: We will introduce examples in the order of phenomenon, cause, and countermeasure. ■ Swelling: The rubber becomes soft, and the O-ring increases in size overall. The fluid used penetrates the rubber material → Change to a suitable rubber material. ■ Extraction: The rubber becomes hard, and the O-ring decreases in size overall. The plasticizer contained in the rubber material is extracted by the fluid used → Change to a suitable rubber material. ■ Permanent deformation: The O-ring is crushed and does not return to its original shape. The operating temperature is too high / The crush depth is too large → Change to a rubber material with good heat resistance / Review the groove dimensions or O-ring dimensions. ■ Overhang: The O-ring is torn either completely around or partially. It overhangs the gap between the groove and the mating surface and tears at the edge of the groove → Reduce the gap with the groove / Use a high-hardness O-ring or combine with a backup ring, etc. * Samples are available upon request. If you would like a sample, please apply through [Contact Us]. * Product documentation can be viewed from [Download].
