?NBR rubber U-shaped rubber seals

??NBR rubber U-shaped rubber seal with good resistance to oil, water resistance, solvent resistance and resistance to high pressure oil properties. With good compression distortion, wear and elongation force. NBR rubber (NBR) U-type rubber seals made of acrylonitrile and butadiene polymerization, acrylonitrile content from 18% to 50%, the higher the acrylonitrile content of the hydrocarbon fuel of petrochemical oil resistance better, but the low temperature performance is poor, the general temperature range of -25 ~ 100 ?. NBR rubber and rubber ring seal is currently one of the most commonly used rubber.

??U-shaped rubber seal is mainly used in the hydraulic cylinder rod seals, nitrile rubber U-shaped rubber seals are proven elements, due to its good mechanical properties used in a standard cylinder construction, particularly for poor work engineering machinery hydraulic cylinder under the conditions.

??RU2 series U-shaped lip seal ring is a compact structure. Compact RU2 U series is designed for small-ring groove design. It is particularly suitable for use in space-saving design.

??Even if the system pressure is very low, this compact form can still provide a good seal, U-shaped rubber ring seal in the region two dynamic sealing lips. Structure with two sealing lips improves the leakage characteristics of the low pressure system. Since the line between the two sealing lips into a reservoir chamber, when the system pressure is higher than 10 MPa, the friction was able to be reduced accordingly.

??In addition, the second sealing lip to prevent dirt from entering the system from atmospheric measurements

??U-shaped ring -RU2 Series U-ring - NBR rubber advantage of the U-shaped rubber seals

??Both high and low pressure under good sealing effect,

??Good wear resistance, low wear - from sudden impact load,

??- Suitable for small trench - easy to install.

??NBR rubber U-shaped rubber seals disadvantages:

??Not suitable for polar solvents being, such as ketones, ozone, nitro hydrocarbons, MEK and chloroform. · For the production of the fuel tank, oil tank and lubricating oil in the oil-based hydraulic oil, gasoline, water, silicone grease, silicone, titanium esters, glycol-based hydraulic fluid medium oil used in rubber parts, especially the sealing parts .

??NBR rubber seals can be said is the most widely used and lowest cost rubber seals.
