o-ring kit NBR70 o-ring seal box service seal o-ring 30 size oring kit set

Short Description:

O-ring O-ring (O-rings) is a kind of rubber sealing ring with a circular cross-section. Because its cross-section is O-shaped, it is called an O-ring 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.

Our advantage

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 advantages

1. O-rings are the components of choice for many manufacturers; not only because of their relatively low cost to manufacture, but also because of their myriad other benefits.

2. O-rings can form seals over a wide range of temperature, pressure and tolerance levels. They do not require any critical torque when tightening and are therefore unlikely to cause damage to the structure.

3. The O-ring will naturally return to its original shape when pressure is applied to the cross section, so it has been proven to be very reliable and strong.

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
