Introduction for O Rings

 

An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop

of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly

between two or more parts, creating a seal at the interface.

The O-ring may be used in static applications or in dynamic applications where there is relative motion between

the parts and the O-ring. Dynamic examples include rotating pumpshafts and hydraulic cylinder pistons.

O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make,

reliable, and have simple mounting requirements. They can seal tens of megapascals (thousands of psi) of pressure.

 

Function of the rubber o ring

 

O-Rings are used in sanitary pipeline systems for the Auto, Machinery, Food, Dairy, Beverage, Pharmaceutical

and Bio-Tech industries. Rubber Fab offers a full line of AS568 dash numbers, metric, and specialty o-ring sizes

that are manufactured using EPDM, NBR, FKM Fluoroelastomer, Buna-N, PTFE, Silicone and so on.

 

The o-rings used in cylinder, pump, railcars, truck, washing machine, instrument and meter, mine equipment,

pipeline, household appliances, automobile, steamboat, industrial electrical equipment, building door& window,

construction machinery, construction bridges and tunnel.

 

1. mechanical sealing, pressure vessel ,gas compressor, reaction vessel ,heat

 

exchanger, boiler, filter and so on.

 

2.it can be used for all kinds of electronic products in a wide range ,such as camera, mobile phone, printer,

computer.

 

3. Used for automobile windows and doors, etc...

 

4. Silk screen printing, spray coating, laser etching, back-lighted, hard/epoxy coating keypads.

 

 

 

O-ring for installation on a variety of machinery and equipment, at a specified temperature, pressure, and various

liquid and gaseous media, at rest or in motion from the seal. On the machine, marine, automotive, aerospace

equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining

machinery, petroleum machinery, plastic machinery, agricultural machinery, and a variety of instruments, a large

number of applications for various types of seals elements. O-ring is mainly used for static seals and reciprocating

seals. For rotational movement of the seal when limited to low-speed rotary sealing device. O-ring is usually

installed on the outer or inner circle from the seal section is rectangular trench. O-ring seals still play a good shock

absorption in oil, acid, wear, erosion and other environmental chemistry. Therefore, O-ring hydraulic and pneumatic

drive system most widely used a seal .

temperatures up to 300 ℃ and down to -100 ℃.

Silicone rubber performs well under environmental and temperature extremes. It is usually applied in automotive

and aerospace industries where flexibility and longevity are important. It is also a suitable material for parts that

need food grade for food handling equipment and appliances.
