High quality PU O ring customized plastic rubber PU O ring sealing ring

O-ring is a common sealing element, which is widely used in mechanical design. The commonly used materials

include nitrile rubber, fluororubber, EPDM, silicone rubber, etc. when selecting the type, we need to pay attention

to the operating conditions, temperature, medium and other factors, and select the appropriate material in

combination with the specific operating conditions to ensure the service life.

(1) the sealing part is simple in structure, the installation part is compact and the weight is light.

(2) has a self-sealing effect, often only one seal can complete the sealing.

(3) good sealing performance, used as a static seal can almost be done without leakage.When used for

reciprocating movement, the sealing performance is unchanged in the reciprocating journey, and the leakage

is very small, and only some leakage occurs when the speed is high.

(4) the movement of friction resistance is very small, for the occasion of alternating pressure can also adapt.

(5) Size and groove standardization, low cost, easy to use and outsourcing.

An O-Ring is a simple and versatile ring-shaped packing or sealing device with a circular cross section.

The opposite side of an O Ring are squeezed between the walls of the cavity or gland into which the O - Ring is

installed. The zero clearance within the gland provides an effective sealing and blocking the flow of liquids, and

gases through the glands. Internal pressure dynamics and static.

Application field of PU O ring

O-type rubber sealing ring is widely used in diesel locomotive, automobile, tractor, construction

machinery, machine tools and various hydraulic and pneumatic components and other seals, can undertake the

sealing of fixed, reciprocating and rotating movement, in the seal of mechanical products .

O-type rubber sealing ring accounts for more than 50%. According to the needs, we can produce various special

purpose sealing rings and special-shaped rubber sealing products for high temperature, low temperature vacuum,

high pressure and different media

For injection molding, the products will be sent for 15 days. And we support OEM and ODM.
