High Quality O-Ring Seal Box Kit

Short Description:

O-ring O-ring is a rubber sealing ring with a circular cross-section. Because of its O-shaped cross-section, it is called an O-shaped rubber sealing ring, also called an O-ring. It began to appear in the mid-19th century, when it was used as a sealing element for steam engine cylinders. O-rings are the most common mechanical design for seals because of their low cost, simplicity of manufacture, reliable function, and simple installation requirements.

What is an O-ring

The O-ring is a kind of extruded seal. The basic working principle of the extruded seal is to rely on the elastic deformation of the seal to cause contact pressure on the sealing contact surface. If the contact pressure is greater than the internal pressure of the sealed medium, it will not occur. leaks, and vice versa.O-rings are often used in pump equipment and are widely used seals in hydraulic and pneumatic systems. It has good sealing performance and can be used for both static sealing and dynamic sealing; it can not only be used alone, but also is a basic component in many combined sealing devices. It has a wide range of applications, and if the material is selected properly, it can meet the requirements of various media and various sports conditions.

O-ring advantages

1. Simple structure, small volume and compact installation location.
2. It has the function of self-sealing, no need for periodic adjustment.
3. Good sealing performance, no leakage during static sealing.
4. The frictional resistance of movement is small, which is suitable for occasions with alternating pressure.
5. The size and groove have been standardized, the price is cheap, the product is easy to obtain, and it is easy to use and purchase.
6. Strong adaptability and wide range of uses.

material	Low TEMP.	High TEMP.	Performance
NBR	-40	120	Good resistance to alcohol,amines, petroleum oils, and gasoline over a wide range of temperature. Also good resistance to caustic salts and fair acid. Poor in strong oxidants, chlorinated hydrocarbons, ketones, and esters
HNBR	-25	140	HNBR is made from NBR by hydrogenation. It has high temperature resistance, abrasion resistance and good physical properties.
ACM	-25	150	It is used in diaphragm, hose for automotive application. Good resistance to heat, ozone and oil. Generally attacked by water, alcohol, glycol and aromatic hydrocarbons. The molecular structure contains ethyl acrylate (EA). Butyl acrylate (BA), and methoxy ethyl acrylate (MEA). High BA content get better low temperature resistance, and high MEA content get more oil resistance.
EPDM	-40	125	Stable in polar fluids (alcohol, ketone, and glycol), and hydrochloric acid. Due to the low specific gravity, it can compound with large amount filler.
VMQ	-60	125	The most widely temperature ranges for application. Good weather and ozone resistance, but poor mechanical property and chemical resistance.
FKM	-20	250	Fluoroelastomers have a high degree of chemical stability and are currently the best media resistance of any elastomer. Type 26 fluoroelastomer resistant to petroleum-based oils, diester oils, silicone ether oils, silicic acid oils, inorganic acids, most organic, inorganic solvents, drugs and so on
