HIGH VISCOSITY LUBRICANT U4 Resistant O-Rings and Seals
High Viscosity Lubricant U4, also known as polyalphaolefin (PAO) or synthetic oil, is a type of synthetic lubricant primarily used in industrial applications such as manufacturing, automotive, and aerospace. It is commonly used as a base oil in gear oils, hydraulic oils, and engine oils. Common uses for this lubricant include lubrication of bearing surfaces, hydraulic systems, and metalworking processes.
When rubber is exposed to High Viscosity Lubricant U4, it is prone to swelling and softening due to the high viscosity of the lubricant. This can cause the rubber to become brittle, reducing its flexibility and elasticity, and can potentially cause it to crack or tear. Additional risks include leaching of the lubricant into the rubber, which can cause it to become brittle, and may also reduce the overall performance of the rubber seal.
