Product Description
Polyurethane PU Material Hydraulic Composite Kdas Tpm Dpm Das dBm POM Piston Oil Seal1. KDAS combined sealing ring is a two-way piston sealing ring. This combined sealing ring is composed of an elastic rubber ring, two additional retaining rings and two wear-resistant rings. This design provides a compact solution that combines sealing and guiding, and is suitable for a combined sealing ring installed in a closed groove. The combined sealing ring includes an elastic toothed sealing ring, two retaining rings and two wearresistant rings. In the middle, there is a sealing element that really plays a role of sealing; and a retaining ring and a wear ring are placed on each side.The retaining ring prevents the sealing ring from being squeezed out into the gap; the middle sealing ring is a toothed sealing ring, which can play a good sealing role when it is still and in motion. The function of the wear ring is to guide the piston in the cylinder and bear the radial force.
2. Application range of KDAS combination oil seal
KDAS combined sealing rings are often used as sealing elements in reciprocating hydraulic cylinders and pistons, such as light bulldozers, injection molding machines, blow molding machines, cranes, forklifts, hydraulic gates and agricultural machinery

DIFFERENT FROM NBR FROM HNBR
ITEM | NBR | HNBR |
Density, g/cm3 | 1.3 | 1.3 |
Elongation at Break, % | 380 | 300 |
Maximum Temperature Mechanical, °C | 110 | 190 |
Strength to Weight Axial, points | 3.9 | 4.1 |
Strength to Weight Bending, points | 12 | 12 |
Tensile Strength Ultimate (UTS), MPa | 18 | 19 |
Acrylonitrile Butadiene Rubber (NBR), usually shortened to Nitrile, was developed in 1941 as the first oil resistant rubber. Grades with high acrylonitrile content have better oil resistance whereas low acrylonitrile content gives better low temperature flexibility and resilience.
- Nitrile has moderate physical properties but good abrasion resistance. Gas permeability is low.
- Ozone resistance and electrical properties are poor.
- Flame resistance is poor and it is not suitable for use with use with polar solvents (e.g. MEK).
- Certain grades can be compounded with PVC to improve ageing, flame, petrol and ozone resistance.
- Carboxylated grades of Nitrile (XNBR) have improved physical properties and higher temperature resistance.
- Potable water (WRAS) compounds are available as well as mixes suitable for use in the food and pharmaceutical industries.
- Typical applications include accumulator bladders, diaphragms, gaskets, hose, liners, O-rings and seals.
- Typical working temperature range: -25°C to +100°C. Low acrylonitrile materials good down to -50°C & peroxide cured materials up to +150°C.
- Hydrogenated Nitrile Rubber (HNBR) properties depend upon the acrylonitrile content and the degree of hydrogenation of the butadiene copolymer.
- They have rather better oil and chemical resistance than Nitrile Rubber and can withstand much higher temperatures.
- HNBR has excellent resistance to sour oil and gas, steam, hot water and ozone.
