The German DIN 3771 standard refers to all O-rings as sealing elements for fluid technology and identifies O-Ring sizes by their Inner Diameter (ID) &Cross Section (C/S). This standard has essentially been incorporated into the international standard ISO 3601 which sets the globally relevant O-ring dimensions and uniform rules for installation spaces and the properties of the O-rings. It defines metric O-rings according to the same dimension chart as DIN 3771 while it has been extended to include O-rings in imperial dimensions. ISO 3601 also goes beyond the German standard in the area of materials containing material requirements for O-rings that far exceed those of DIN 3771.

Elastomer materials suitable for certain sealing situations are referred to by their abbreviation according to DIN ISO 1629 and include: 

Nitrile/Buna-N (NBR), presently the seal industry’s most widely used elastometer, Ethylene-Propylene (EPM/EPDM) used extensively for outdoor, weather-resistant uses and water applications, 

Silicone (MQ, PMQ, VMQ, PVMQ) especially resistant to high, dry heat in primarily static applications, 

Neoprene® (Chloroprene) (CR) developed as oil-resistant substitute for natural rubber with resistance to ammonia and Freon® and therefore a superior sealing material for the refrigeration industry, 

Fluorocarbon compounds (FPM / Viton®) / (Fluorel®) (FKM) combining high-temperature toughness with wide chemical agent compatibility, and 

Fluorosilicone (FVMQ) combining the good high and low temperature stability of silicones with the fuel, oil and solvent resistance of fluorocarbons.

ISO 3601 / DIN 3771 standard O-rings are offered as part of our own (AVIATIONEU NEW ERA) product lines. Sourced from quality manufactuurers they are supplied in competitively priced packs in different materials, sizes, and hardnesses as specified by a two-digit Shore A durometer number,ranging from 20 (soft) to 90 (hard), depending on the type of elastomer.

Preformed packings are basically a type of O-ring providing effective sealing over wide ranges of pressure, temperature, and movement, with the advantage of sealing pressure in both directions and reducing friction and wear on moving parts. They are used to prevent leaks and improve aircraft performance. The packings are formed prior to shipping and they are supplied ready to use. Compared to form-in-place gaskets, they offer easy installation without sacrifising performance. Typically made of a slightly flexible material that can be compressed to create a better seal.

The selection of a specific O-ring is based on a variety of factors, including fluid media resistance, temperature range, hardness, durability, gland size, static or dynamic application, etc. 

An extensive selection of preformed packings to choose from can be supplied as part of OEM brands or sourced from quality manufacturers and offered as part of our own (AVIATIONEU NEW ERA) product lines. They are made from different materials such as Nitrile/Buna-N (NBR), Butadiene (Synthetic) Rubber (BR), Flurocarbon (Viton®) rubber  and others. Conform to various Military, Aeronautical & other Standards. They come in different  Metric or Imperial (inch) sizes (internal/outer diameters and thicknesses (cross-sections) , and hardnesses to suit application needs. 

For brief presentations of our offered packings please consult the Product Description Section or contact us for further information.

Flurocarbon rubber compounds (also known as FPM, FKM, or trade names Viton®, Fluorel®, Technoflon®, Dai-El® ) combine high-temperature toughness with wide chemical agent compatibility,  and feature excellent resistance to petroleum products and solvents and good high-temperature compression set characteristics. The designations FPM, FKM and Viton® very often cause confusion although they all relate to one single base material. FPM is the international abbreviation according to DIN/ISO, FKM is the short form for the fluoroelastomer category according to the American standard ASTM while Viton® is the registered trade mark of DuPont Performance Elastomers.

M83248 series Flurocarbon rubber o-rings feature an extremely high fuel and heat resistance and they ideally suited for aircraft fuel system applications. These o-rings feature a high temperature resistance, excellent resistance to acids, fuels, mineral and vegetable oils and greases, aliphatic, aromatic and chlorinated hydrocarbons, non-flammable hydraulic fluids (HFD) and many organic solvents and chemicals, low swelling in ASTM oil No. 1, and IRM 902 and IRM 903, excellent resistance to aging and ozone as well as low gas permeability and low compression set.

Flurocarbon rubber o-rings are often used in place of those made by Nitrile rubber (NBR) also known as Buna-N, presently the seal industry’s most widely used elastometer. When it comes to selecting Buna (NBR) vs. Flurocarbon (Viton®)  for sealing applications, the selected material should be selected on the basis of the intended application. Viton and Buna are two durable, elastomer materials and they are both commonly used in sealing applications for O-rings and gaskets. 

M83248 series Flurocarbon rubber o-rings are offered as part of our own (AVIATIONEU NEW ERA) product lines. Sourced from quality manufactuurers they are supplied in competitively priced packs in different sizes.

O-rings (also termed as Preformed Packings) offer effective sealing over wide ranges of pressure, temperature, and movement, with the advantage of sealing pressure in both directions and reducing friction and wear on moving parts. The selection of a specific O-ring is based on a variety of factors, including fluid media resistance, temperature range, hardness, durability, gland size, static or dynamic application, etc. The use of O-rings as gaskets or static seals permits metal-to-metal contact and allows almost unlimited pressures under extreme vibration. All O-rings should be lubricated before installation and constant lubrication should be provided for running seals to avoid excessive wear. Sharp edges, threads, and cross-drilled ports over or through which rings must be installed should be avoided.

An extensive selection of O-rings can be supplied as part of OEM brands or sourced from quality manufacturers and offered as part of our own (AVIATIONEU NEW ERA) product lines.
