What is O-ring

<p><a href="https://www.jdoseal.com/jdseal-nbr-fkm-vmq-o-ring" rel="noopener noreferrer" target="_blank">O ring</a> is a kind of rubber ring with a circular cross-section. Because its cross-section is O-shaped, it is called O-ring. It is the most widely used one in hydraulic and pneumatic transmission systems. Usually called O Ring in Taiwanese and Japanese companies.</p><p><br></p><p>O ring is an annular rubber sealing ring with a circular cross-section. It is mainly used for mechanical parts to prevent the leakage of liquid and gaseous media under static conditions. In some cases. O-ring can also be used for axial reciprocating motion And the dynamic sealing element of low-speed rotating motion. According to different conditions, different materials can be selected to suit it.</p><p><br></p><p>O-rings are usually selected as large cross-section O-rings as possible. In the case of the same gap, the volume of O-rings squeezed into the gap should be less than the maximum allowable value of squeezed into.</p><p><br></p><p>&nbsp;For different types of fixed sealing or dynamic sealing applications, o-ring seals provide designers with an effective and economical sealing element. O ring is a two-way sealing element. The initial compression in the radial or axial direction during installation gives the o-ring its own initial sealing ability. The sealing force produced by the system pressure and the initial sealing force form the total sealing force, which increases as the system pressure increases. The o-ring shows a prominent role in static sealing occasions. However, in appropriate dynamic occasions, O-rings are often used, but it is limited by the speed and pressure of the seal.</p>
