• Forged and tempered base material with high strength, resistant to warping under high pressure pulsation
• Split two-piece design for easy disassembly, saving service time for hydraulic maintenance
• Precision milled sealing surface for tight fit, stable sealing with O-ring and reliable pressure resistance
• Black anti-rust coating against mud and water corrosion for harsh site environment
• Replace flange individually instead of whole hose assembly to reduce spare part cost
• Flaw detection before delivery to eliminate internal casting defects for safer high-pressure operation
• Perfectly compatible with original hydraulic flange joints of ZL50G/ZL50GL

FAQ 

Q1: Can this split flange fit ZL50GN loader directly?
A1: Part No.803164271 is specially for ZL50G and ZL50GL. ZL50GN adopts different hydraulic flange specification. Direct interchange is not recommended. Verify old part number before ordering.

Q2: Can a flange with dents or scratches on sealing surface continue to be used?
A2: Damaged sealing surface will cause persistent oil leakage with high risk under high pressure. Replacement is required.

Q3: Are bolts and sealing rings included?
A3: Standard package only contains split flange. Bolts and O-rings are optional parts. You can order them separately.

Q4: How to deal with oil leakage after installation?
A4: Check whether bolts are tightened evenly and check if O-ring is aged or misaligned. Replace flange if sealing surface is scratched.

Q5: What should be noted during installation?
A5: Align two half flanges, tighten bolts diagonally and evenly to avoid uneven stress. Place O-ring properly to prevent pinching. Follow torque requirement and avoid over-tightening.
