Suggested storage environment for rubber products:The ambient temperature should not exceed 120. F(49ºC);Store in the dark (especially sunlight); Stay away from working environments with oxidation; Keep away from the working area of radioactive equipment;Sealed (especially oxygen) storage;Stay away from chemical pollution sources. 2 Correct Installation MethodsAfter installation, a close and careful inspection should be carried out to replace the "O" - shaped sealing ring with scratches or punctures. Excessive stretching during installation can cause cracks or expansion of the "O" - shaped sealing ring, which is easy to detect.Install O-ring seals with concave or irregular surfaces, with a certain gap and taper between the inner and outer diameters. 3 Methods to prevent compression deformationThere are three methods to prevent compression deformation:Choose a rubber formula with good performance and the ability to continuously restore to its original form.Use a specialized "0" - shaped sealing ring assembly tool to ensure that the "O" - shaped sealing ring is compressed properly. Properly store the "O" ring sealing tool so that the weight of the heavy shaft shaped component or spindle does not act on a single point or surface of the "O" ring. 4. Prevent damage caused by squeezing into the sealing gapThe sealing ring was recorded in the sealing gap, causing the sealing ring to peel off and be damagedChoose the correct rubber formula. It is best to use the "O" - shaped sealing ring recommended by the provider.Check the diameter of the O-ring groove and the tool. The tool connection eccentricity may sometimes cause the "O" ring seal to have excessive clearance at a certain point.Use support rings to increase the pressure resistance of the "O" - shaped sealing ring. 5. Prevent the support ring from squeezing into the sealing gapThe "O" - shaped sealing ring support ring is mainly made of fiberglass PTFE and fiberglass PEEK. Fiberglass PEEK support ring has good tensile properties at high temperatures.When using a support ring with a concave surface, the inner and outer edges of the concave surface expand outward as pressure increases, increasing the pressure holding capacity of the "O" - shaped sealing ring and support ring arrangement. 6. Prevent the "O" ring from losing sealing at low temperaturesWhen rubber approaches its glass transition temperature, it loses its elasticity. Different polymer rubbers lose their elasticity at different temperatures, but their elasticity decreases at lower temperatures. Therefore, when selecting rubber formulations, low-temperature sealing requirements must be considered. 7. Prevent wear and loss of sealing of the "O" ringShort term sealing of low-speed moving parts. Use a sealing surface with a smoothness of less than 62RMS and an O-ring groove with a smoothness of 125 RMS.Long term sealing of high-speed moving parts. The processing smoothness of the sealing surface shall not be less than 5 RMS.Prevent abrasive particles such as sand from entering the working fluid. Filter the working fluid or wrap a filter screen around the tool to prevent abrasive particles in the working fluid from contacting the sealing surface and "O" ring.
