1. Performance and use

It consists of 4 parts, the upper middle is a rubber star ring, the lower is a rubber O-ring, and the middle is a filled PTFE sealing slip ring. Suitable for bidirectional sealing of reciprocating pistons. It has the double safety of low friction and high elasticity, low gas permeability, and good dynamic and static sealing performance. Larger extrusion gap is allowed, used for cylinders with high pressure, strict requirements on position or pressure maintenance, and not particularly fast moving speed (<0.5m/s), such as press cylinder, supporting cylinder, clamping cylinder, positioning Cylinders, piston accumulators, etc. Especially recommended for heavy duty and large diameter applications. In high-pressure applications, the friction coefficient is small, the sliding performance is good, and there is no creeping phenomenon. The groove structure is simple and easy to install.

The adaptability of the working medium and the working temperature range can be changed by changing the material of the O-ring and the star-shaped ring.

Adapt to the one-piece piston, the installation groove is small, which is beneficial to the design of the cylinder size.

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 contact us for details.

O-ring, star ring: nitrile rubber NBR, fluorine rubber FKM. The material is determined according to the temperature and working medium of the working condition, if you are not sure, please contact us.

3. Precautions:

Ⅰ. If other parameters of the matched O-ring are qualified, the diameter of the ring is 1-2% different from the value listed in the sample, which will not affect the use.

Ⅱ. When installing, be careful not to twist the O-ring.

Ⅲ. Before installation, use tooling or hot oil to expand the slip ring, and return it to its original shape after installation.

Ⅳ. The product size table is some commonly used products, and other specifications are also available.
