SEAL - UCUP (Nissan NICK1780359)

A worn seal can allow fluid leakage, reducing system pressure and causing erratic operation. The SEAL - UCUP is an aftermarket replacement part, cross-referenced to Nissan part number NICK1780359. This type of seal functions by creating a static or dynamic barrier between two surfaces. Its primary mechanical role is to prevent the passage of fluids or contaminants along a shaft or bore. A common failure consequence is gradual loss of lubricant, which may lead to increased friction and component wear. In a typical usage context, this seal is installed in a gland or housing to retain fluid under moderate pressure. Verify the serial number or application, then call (562) 693-7748.
