Factory Direct High Quality Complete O-Ring Kit 421Ts 666PCS DH-200 DH-220 DH-320

Short Description:

Rubber O-rings are mainly used for static sealing and reciprocating sealing. When used for rotary motion seals, it is limited to low-speed rotary seals. The rubber O-ring is generally installed in the groove with a rectangular cross-section on the outer or inner circle to play a sealing role. Rubber O-rings still play a good role in sealing and shock absorption in environments such as oil resistance, acid and alkali resistance, grinding, and chemical erosion. Therefore, the rubber O-ring is a widely used seal in hydraulic and pneumatic transmission systems.

Specification

O-ring

Standard size

O-ring

The cross-sectional structure of the rubber O-ring is extremely simple, and it has a self-sealing effect and reliable sealing performance. Since the structure of the rubber O-ring itself and the installation part are extremely simple and standardized, it is very easy to install and replace. Low hardness and easy installation, but prone to peeling, installation damage, extrusion and even pressure. The hardness is too high and the installation is inconvenient.

O-ring advantages

1. Low cost non-oil resistant material.

2. Good water resistance, good elasticity below 70 hardness.

3. When the hardness is high, it has poor compression distortion.

4. Most neutral chemicals and dry and moisturizing organic ketones can be used

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
