Custom Degisn AS568 All Colorful HNBR Rubber O-Rings Seal
Product Description
The O-Ring is one of the most basic and functional seals ever made and is the backbone to all the hydraulic and sealing applications in the world. An O-Ring is a solid-rubber seal shaped like a dough nut or torus. When compressed between mating surfaces, an O-Ring blocks the passage of liquids or gases. O-Rings are available in a wide range of standard and non-standard sizes that are suitable for nearly all sealing applications.
O - ring is mainly used for static seal and reciprocating motion seal. For rotary motion seal, limited to low speed rotary seal device. O-type sealing ring is generally installed in the outer circle or the inner circle on the rectangular section of the groove to seal.
O ring in oil, acid and alkali, wear, chemical erosion and other environments still play a good sealing, shock absorption role. Therefore, O-ring is the most widely used seal in hydraulic and pneumatic transmission system.
O Ring Seal Materials : NR , SBR , BR , IIR , EPDM , CR , XNBR , NBR , HNBR , PU , CSM , ACM(PA) , ECO , VAMAC , SIL , FSIL , FPM / FKM.
Silicone:The term silicone covers a large group of materials in which vinyl-methyl-silicone (VMQ) is often the central ingredient. Silicone elastomers as a group have relatively low tensile strength, poor tear and wear resistance. However, they have many useful properties as well. Silicone has a good heat resistance, good cold flexibility, and good ozone and weather resistance as well as good insulating and physiologically neutral properties.
HNBR:Hydrogenated Nitrile Butadiene Rubber, also known as Highly Saturated Nitrile (HSN), is produced by hydrogenating acrylonitrile butadiene rubber (NBR).This process improves the heat and ozone resistance, increases tensile strength, and provides superior abrasion resistance. The result is a rubber polymer that performs superior to standard NBR in most sealing applications. Taking advantage of its inherent properties, HNBR can be compounded to provide excellent service life in applications such as oilfield, automotive, and refrigerants. Dynamic applications requiring long service life or in abrasive environments are especially well suited to HNBR. FDA grades are available. Internally lubricated compounds are superior for extended wear dry air applications.
HNBR O-Rings are most commonly in Green or Black, are also avaialable in Yellow and red special compounds.

| NSF |  | NSF is specialized in standard setting, product testing and certification services in the fields of public health, safety and environmental protection, and is an authoritative body in the field of public health and safety |
| KTW |  | The supplier is required to comply with DVGW (German Gas and Water Association) Regulation W 270 "Propagation of microorganisms on Non-metallic materials". This standard mainly protects drinking water from contamination with biological impurities. All drinking water systems and excipients exported to Europe must be KTW certified. Therefore, if Chinese drinking water systems and excipients are to be exported to European countries, they must pass KTW certification. KTW has been authorized by the World Health Organization (WHO) for the certification of safe drinking water. |
| WRAS |  | WRAS(Water Regulations Advisory Scheme) certification refers to the Water Regulation Advisory Scheme. WRAS is the certification of the safety of drinking Water in the UK. |
| UL |  | Founded in 1894, UL has become one of the world's leading testing and certification organizations with a complete set of management systems, standard development and product certification procedures. |
| SGS |  | SGS certification refers to the service that SGS performs compliance certification on targets according to standards, regulations, customer requirements and other conditions. To carry out relevant certification, we must pass inspection, testing, authentication, certification and other means (SGS certification itself is not a certification, but refers to the certification service of SGS). |
