How to install nitrile rubber O-ring?

The characteristics of nitrile O-rings: Nitrile rubber has good oil resistance, high wear resistance, good heat resistance, and strong adhesion. Its disadvantages are poor low temperature resistance, poor ozone resistance, low insulation function, and slightly lower elasticity. It can be used for a long time in the air at 120°C or in the oil at 150°C. In addition, it also has good water resistance, air tightness and excellent bonding function.



As one of the effective conditions for the sound cutter in the sealing equipment, the nitrile rubber O-ring is also very important for its preservation. When storing the newly purchased sealed sound cutter, ensure that the sound cutter is isolated from the external environment as much as possible to prevent corrosion or abrasion due to the influence of Yiwangqiuqinju. During the installation process, attention should also be paid to the steady movement of these basic conditions to prevent foreign matter from entering and forming a sealed environment. In the state where O-rings are stored and installed, the following requirements should be paid special attention to to prevent damage to the normal operation and quality of O-rings.
Require special clarification
1 NBR O-rings will occasionally show discoloration during storage, that is, white powder is produced on the surface of the O-rings. This situation will not adversely affect the performance of the O-rings.
2. Prevent strapping and hanging on needles or metal wires to avoid O-ring deformation and lip end damage.
3. Try not to open the original packaging of the O-ring when it is not in use, to avoid dust and foreign matter on the O-ring that may cause damage to the O-ring.
4. When installing, consider coating the groove and O-ring with sealing medium.
5. Try to prevent direct sunlight or place near high temperature heat sources such as boilers to avoid aging of O-rings.
6. When installing into the groove, be careful not to twist the O-ring.

The final thing to pay attention to is that the nitrile rubber O-ring is a disposable sealing material, and the wear will not be restored after use. Therefore, the replaced O-ring is still in good condition, but it is under pressure to a certain extent. It has already shown a decline in functionality, so it cannot be used again. Regular replacement of new O-rings is conducive to the accuracy of the fracture of sexual reproduction of the sealed sound-cutter, and prolongs the service life of mechanical parts.
