Part number 6P7985 also referenced as 6P-7985 is a high performance PTFE ring seal wearing designed specifically for the hydraulic systems of excavators and loaders. As a specialized hydraulic seal component, 6P7985 6P-7985 stands out for its use of premium PTFE material, which brings exceptional wear resistance and low friction performance—key features needed to handle the high pressure and frequent motion of hydraulic cylinders in excavators and loaders. Unlike ordinary ring seals, 6P7985 6P-7985 is engineered to fit seamlessly into the hydraulic cylinders of various excavator and loader models, ensuring long lasting leak free operation even in harsh working environments like construction sites and mines.

The outstanding performance of 6P7985 6P-7985 comes from its advanced material selection, precision design and strict manufacturing standards—all tailored to meet the demanding needs of excavator and loader hydraulic systems.

6P7985 6P-7985 is made from high quality PTFE (Polytetrafluoroethylene) with added glass fiber reinforcement. This material combination gives 6P7985 6P-7985 several key benefits. First, it has an extremely low friction coefficient, ranging from 0.02 to 0.04, which reduces the resistance between the seal and the cylinder wall during movement. This not only improves the response speed of the hydraulic cylinder but also lowers energy consumption of the entire hydraulic system. Second, the reinforced PTFE material provides 50% higher wear resistance compared to standard PTFE seals. This means 6P7985 6P-7985 can withstand the repeated reciprocating motion of hydraulic cylinders in excavators and loaders for a longer time without losing its sealing performance. Additionally, PTFE has excellent chemical stability, so 6P7985 6P-7985 is compatible with all common hydraulic fluids used in excavators and loaders, including mineral based oils and synthetic hydraulic fluids.
