CHECK VALVE KIT(PRIMARY) (Nissan NI691H2-00034)

A worn check valve kit can allow fluid to bypass, reducing system pressure and causing sluggish operation. This aftermarket replacement references Nissan as the OE maker and cross-references part number NI691H2-00034. The check valve kit (primary) controls the direction of flow by opening in one direction and closing against reverse flow. A failed check valve may lead to uncontrolled movement or inability to hold a load in position. During a routine service interval, technicians often inspect the valve seat and spring for wear or debris. The kit includes the necessary components to restore proper one-way flow control. Verify the serial number or application, then call (562) 693-7748.
