4N1828 90° — Cat 320C 320D

This 90° hydraulic fitting connects two hydraulic lines or components at a right angle, essential for routing fluid flow in tight spaces within the hydraulic system. Manufactured to meet robust CTP aftermarket standards, it offers durability and reliable sealing compared to a worn or corroded fitting that could leak. Operators may observe hydraulic fluid leaks around the connection point or a drop in system pressure if this fitting is compromised.

Failure Symptoms

The first indication of a failing 4N1828 fitting is often a visible hydraulic fluid leak at the connection point. If the leak persists or worsens, it can lead to a gradual loss of hydraulic system pressure and reduced equipment performance. Unaddressed leaks can result in insufficient lubrication for hydraulic components and potential environmental contamination.

Installation Tip

Ensure the threads on both the fitting and the receiving port are clean and free of debris before assembly. Do not reuse old sealing washers or O-rings; always use new ones with the replacement fitting.

Service Note

Inspect the connected hydraulic hose and the mating component's port for any signs of wear or damage during the replacement of this fitting.
