O-ring repair kit 1254955 auto parts oil seal, customized size

Short Description:

O-ring O-ring (O-rings) is a rubber sealing ring with a circular cross-section. Because of its O-shaped cross-section, it is called an O-ring rubber seal, also called an O-ring. It began to appear in the middle of the 19th century, when it was used as a sealing element for steam engine cylinders.

O-ring scope of application

O-ring seals are suitable for installation on various mechanical equipment, and play a sealing role in static or moving states under specified temperature, pressure, and different liquid and gas media. Various types of seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters. element. O-rings are mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing devices. The O-ring is generally installed in a groove with a rectangular cross-section on the outer circle or the inner circle to play a sealing role. O-ring seals still play a good role in sealing and shock absorption in environments such as oil resistance, acid and alkali, abrasion, and chemical erosion. Therefore, the O-ring is the most widely used seal in hydraulic and pneumatic transmission systems.

Advantages of O-rings

Compared with other types of sealing rings, O-rings have the following advantages:
--Suitable for various sealing forms: static sealing, dynamic sealing
Suitable for a variety of materials, dimensions and grooves have been standardized, strong interchangeability
-- Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion)
--Suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media
Through the selection of suitable rubber materials and proper formula design, the effective sealing effect on oil, water, air, gas and various chemical media can be realized. The temperature range is wide (- 60 ℃ ~ + 220 ℃), and the pressure can reach 1500Kg/cm2 in fixed use (used together with the reinforcing ring).

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
