1. Performance and use
Suitable for two-way reciprocating rod seals. The leakage is extremely small, and it can be applied in a wide range of media and temperature occasions. The friction force is small, and the servo cylinder that requires quick response is recommended to be preferred.
The adaptability of the working medium and the working temperature range can be changed by changing the material of the O-ring.
The installation groove is small and the groove is simple.
The seal is easy to install and generally requires no special tools.
Comply with GB/T 15242.1-94 and GB/T 15242.3-94 standards.
2. Materials
Sealing ring: Filled with polytetrafluoroethylene (PTFE). According to different working conditions and sealing requirements, different filling materials and filling processes can be selected, please inquire for details.
O-ring: nitrile rubber NBR, fluororubber FKM. The material of the O-ring is determined according to the temperature and working medium of the working condition, if you are not sure, please contact us. If you need to match fluorine rubber (FKM) O-ring, you need to explain before ordering.
3. Precautions:
Ⅰ. If other parameters of the matched O-ring are qualified, the diameter of the ring is 1-2% larger than the value listed in the sample, which will not affect the use.
Ⅱ. When installing, you can bend the sealing ring into a heart shape and put it into the groove, but there must be no creases. In the two cases shown in the figure below, A is allowed and B is prohibited.
