Durable Soft Silicone 3 inch rubber O Ring Seals 70 Shore A
Hardness 10 Years Durability
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 .
