Abrasion Resistance Rubber O Ring Set For Petroleum / Aliphatic Hydrocarbons

NBR 382 Pcs 30 Sizes Inch Mertic Seals in Red Rubber O Ring Box

This O-Ring set is made of Black Buna-N, has a durometer of 70A, and includes 382 pieces covering 30 dash sizes. The rings have a Round cross-section and can be used across a wide temperature range from -40 degrees F (-40 degrees C) to 212 degrees F (100 degrees C). The rings come in a plastic storage case designed for organization and portability. Designed for use in a variety of sealing applications, this Buna-N O-Ring set meets standards defined by Aerospace Standard AS568A for quality assurance.

Buna-nitrile can have high tensile strength, as well as abrasion, tear, and compression set resistance. It is compatible for use with petroleum, hexafluoroacetone (HFA), hexafluoro-2-butyne (HFB) and hydrofluorocarbon (HFC) fluids, vegetable oil, alcohol, acids, and aliphatic hydrocarbons. Buna-nitrile is vulnerable to acetone, ethers, esters, ozone, sunlight and weathering, and should not be used in ozone-generating electric motors, welding equipment, or in applications with exposure to UV light.

Technical sealing has been defined by DIN Standards as follows:

• Static Seal - The sealing action created between two mating surfaces with no leakage of liquid or minimal diffusion of gas.

• Dynamic Seal - The mating surfaces have relative movement with minimal leakage of liquid (useful to protect the sealing efficiency, acting as lubricant)

The simple geometry is the main characteristic of an O-Ring which, in conjunction with proper elastomer selection results in a low cost, easy to use and efficient sealing system. Elastomeric materials, when compressed, react like a high viscosity fluid which transmits applied stress in every direction; consequently, the O-Ring serves as a barrier, blocking the leak paths between the sealing surfaces.

O-Rings offer several advantages over other sealing systems: simplicity of construction, standardized seal dimensions, wide selection of materials, suitability for both static and dynamic applications, standard dimensioning of glands, low cost due to high volume manufacturing.

Sealing is always achieved through a positive compression or squeezing action, resulting in a deformation of the O-Ring cross-section. The most important sealing characteristic of an O-Ring is its resistance to compression set or residual deformation.

O-Ring kits consist of a series of o-ring sizes, assembled into one assortment kit for one low price.

Several series of kits are available, in metric, standard and Japanese sizes and come in a variety of compounds. O-Ring kits are convenient, and provide a way to find the exact fit for each of your applications.
