SEAL - SIDE (Mitsubishi MB1039279)

A worn side seal can allow pressurized fluid to bypass, reducing system efficiency and causing erratic operation. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB1039279. The seal functions as a static or dynamic barrier between two mating surfaces, preventing leakage of fluid or gas. A common failure consequence is gradual loss of pressure, which may lead to sluggish or incomplete movement. In a typical usage context, this seal is installed in a confined groove where it must maintain consistent contact under varying temperatures. The item ships at approximately 0.006 POUNDS.
