Overview of Hankuk Viton O-ring

Hankuk Viton Co., Ltd has been manufactured various of Track Link Seal and Packing products such as Excavator Track, Bulldozer Track, Lubricated track Link, Undercarriage Track Link, Cargo Hatch Cover, Chemical Tanker Hatch Cover Packing and Hydrostatic Test.
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 disc-shaped 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 joint may be static, or (in some designs) have relative motion between the parts and the O-ring; rotating pump shafts and hydraulic cylinders, for example. Joints with motion usually require lubrication of the O-ring to reduce wear. This is typically accomplished with the fluid being sealed. O-rings are one of the most common seals used in machine design because they are inexpensive and easy to make, reliable, and have simple mounting requirements. There are variations in cross-section design other than circular. These include O-rings with x shaped profiles, commonly called x-rings or quad rings. When squeezed upon installation, they seal with 4 contact surfaces - 2 small contact surfaces on the top and bottom. This contrasts with the O-ring's comparatively larger single contact surfaces top and bottom. X-rings are most commonly used in reciprocating applications, where they provide reduced running and breakout friction and reduced risk of spiraling when compared to O- rings.

Design Type
Domestic Standard type of the oil seal (KS B-2804)
Design type of the imported oil seal (Design Type)
They have the system to supply the oil seal manufactured by domestic and foreign company such as National Oil Seal, Freudenberg-NOK etc.
Selection of oil seal
General oil seal may have a problem with the sealing function use of high pressure, high-speed, high temperature, chemicals, when designing the structure and materials of oil seal is suitable for special use must be checked.
Seal selection for design & manufacturing: Fluid, temperature, pressure, rotation speed, environmental conditions
Rotary Seal - Quad Ring, Teflon Lip Seal
Teflon lib seal is ideal as a high pressure rotation seal that has low friction coefficient, good abrasion resistance, good chemical resistance, and excellent to the oil less and dry running state, has good endurance. Maximum service temperature 2600 °C
