A Seal O Ring ensures that there are no gaps or openings through which the lubricating fluids could potentially leak out of the tank. The compressive force exerted by the O-Ring, when installed in the tank's groove, helps to withstand the internal pressure of the lubricating fluids, further enhancing the sealing capability. It is made from nitrile rubber compatible with the lubricating fluids, additives, and other chemicals present in the system to prevent degradation.Attributes:• Helps to keep out contaminants, dust, and other external elements• Provided with nitrile butadiene rubber shore 60 indicates a relatively firm and rigidApplications:A Seal O Ring creates a barrier between the mating surfaces of the lubrication tank, preventing the lubricating fluids from leaking or escaping the tank. The elasticity of the rubber material allows the creation of a tight, leak-proof barrier.
