Factory direct sale high quality excavator oil seal o-ring kit or rubber box 447 pcs factory price

Short Description:

O-rings are mechanical washers consisting of a continuous ring of material. Although they are very simple components, they perform very important work and are widely used in many different fields. They are an important part of many devices, instruments and machinery. The O-ring is placed in the groove and then compressed to form the seal. This prevents liquid or gas from escaping.

O-ring

Standard size

Our advantage

O-rings are suitable for being installed on various mechanical equipment, under the specified temperature, pressure, and different liquid and gaseous media, to play a sealing role in static or moving states. Various types of seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters. element.

O-ring advantages

1. The frictional resistance of the O-ring is small, and the dynamic and static frictional forces are equal, which is 1/2-1/4 of the frictional force of the "0"-shaped rubber ring, which can eliminate the "crawling" phenomenon of movement at low speed and low pressure.
2. The O-ring is highly wear-resistant, and has automatic elastic compensation function after the sealing surface is worn.
3. Good self-lubricating properties of O-rings. Can be used as oil-free lubrication seal.
4. The O-ring has a simple structure and is easy to install.

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
