Product Features
Safe Anti-misconnection Structure to Protect Hydraulic Components
Built-in anti-connection mechanism under residual pressure. Forced connection is blocked when residual pressure exists inside the male end. Avoid high-pressure impact damage on precision parts such as hydraulic pumps and valves, greatly cutting maintenance costs.
Flat-face Seal & Heavy-duty Housing for Long-term Leak Prevention
Nickel-plated carbon steel housing delivers excellent outdoor rust resistance, wear and impact resistance. Precision flat-face sealing ensures superior tightness after connection to reduce hydraulic oil leakage. Stable performance under variable high & low temperature farm working environments.
Precise OEM Dimension for Direct Replacement, Fits Multiple John Deere Tractors
Manufactured strictly according to original RE322903 dimensions for plug-and-play replacement without pipeline modification. Compatible with mainstream models including 5045D, 5075E, 5100M and full 7R series. Easy to install for farm equipment repair and modification.
