Type and specialty of main rubber used in oil seal

The cold resistance of the oil seal is determined by important factors such as the characteristics of the lip material, the characteristics of the sealing medium, the eccentricity of the shaft, and the speed at start.

HNBR Hydrogenated Nitrile Rubber Catalog

Although hydrogenated nitrile rubber is saturated by hydrogenation, it still maintains the characteristics of original nitrile. It has tensile crystallinity and thus has high strength.

Performance Introduction of Combined Packer

Combination seal is one of the most important downhole tools in petroleum engineering, which is widely used in various production links of oil and gas exploration and development. It is located between the tubing and the hose or between the hose and the borehole wall, and is used to seal off the annular space between the tubing and the hose or between the hose and the borehole wall. Among them, the sealing element (rubber sleeve) made of non-metallic materials such as rubber is the most important device, and there are two types of pressing rubber sleeve that relies on axial pressure to press the seal and expanding rubber sleeve that relies on radial pressure to expand the seal.

What are the sealing ring standards?

Sealing ring according to the material can be divided into nitrile rubber sealing ring, natural rubber sealing ring, neoprene rubber sealing ring, EPDM rubber sealing ring, hydrogenated nitrile rubber sealing ring, silicone sealing ring, fluorine rubber sealing ring, silicon fluorine rubber sealing ring. The sealing ring standard is ID inner diameter * CS wire diameter.
