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.

Buna:Buna-N O-Rings / Nitrile O-Rings / NBR: Buna-N O-Rings are the most widely used o-ring material in the world because of low cost, good mechanical performance with resistance to water, most basic oils, lubricants and some fuels, many pneumatic, hydraulic systems, propane, natural gas and the default choice for basic applications. Buna-N o-rings are not recommended for exposure to sunlight, UV light, ozone and general outdoor weathering or hash chemicals, acids, keytones and many others.

Lowest cost highest inventory general purpose commodity NBR compound. Compare to Parker N1470-70 and N0674-70 and Parco 4200-70 and 4900-70.

Applications: General purpose sealing, Air Tools, Hydraulic fluids, Petroleum based oils, fuels, L.P. gases, Cold Water, Silicone greases and oils, Di-ester base lubricants (MIL-L-7808), Ethylene glycol base fluids (Hydrolubes) and Hydraulic Fluidsand in static and dynamic applications.

Avoid: Brake fluids, ozone and UV light

EPDM:Ethylene-Propylene / EPDM O-Rings: Ethylene propylene rubber is an elastomer prepared from ethylene and propylene monomers (ethylene propylene copolymer). Our stock O-Ring compoundare made with an amount of a third (diene) monomer (ethylene propylene diene terpolymers). Ethylenepropylene-diene rubber (EPDM) produced using a third monomer and is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base. EPDM has outstanding resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight; but it is not recommended for gasoline, petroleum oil and grease, and hydrocarbon environments. This popular rubber compound is usually the first choice for low torque drive belt applications.

Applications: Cold and Hot Water, Steam up to 300°F (149°C), Various Water / Municipalities Applications, Household Appliances, Glycol based brake fluids up to 300°F (149°C), Many organic and inorganic acid, Cleaning agents, soda alkali, potassium alkali, Phosphate-ester based hydraulic fluids (HFD-R), Silicone Oil, Silicone Grease, Many polar solvents (alcohols, ketones, esters), Ozone resistant, aging resistant, weather resistant, Outdoor Applications and Electrical Insulators..

Avoid: Mineral oil products (oils, greases and fuels), Solvents, Aromatic Hydrocarbons, Liquefied Petroleum Gas (LPG), Lubricating Oils, Petroleum Base Gasoline

NBR is mainly used to manufacture oil resistant rubber products. Acrylonitrile content in nitrile butadiene rubber (%) has 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30, 18 ~ 24 and other five kinds. The more acrylonitrile content, the better oil resistance, but cold resistance is decreased. It can be used in 120℃ air or 150℃ oil for a long time. In addition, it also has good water resistance, air tightness and excellent bonding properties. It is widely used to produce all kinds of oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, bushing, flexible packaging, flexible hose, printing and dyeing roller, cable adhesive materials, etc. It has become an indispensable elastic material in automobile, aviation, petroleum, photocopying and other industries.

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.

High temp orings product application:

O-ring is suitable for installation on all kinds of mechanical equipment, in the specified temperature, pressure, and different liquid and gas media, in the state of static or moving sealing.

In machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and all kinds of instruments and meters, a large number of applications of various types of sealing components.

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.

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.

High temp orings product performance:

High temp orings product certificates:

Approvals : SGS , NSF , KTW , WRAS , UL , FDA etc . Special requirement is available.

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)
