Applicable Scenarios

Widely used in quarry, aggregate yard, and earthwork construction sites with heavy loads, dust, and mud splash. It is a basic connection accessory for ensuring reasonable pipeline layout and reliable sealing.

▪ OEM interface dimensions, thread specifications, and bend angle for direct replacement on ZL50G/ZL50GL
▪ Factory thread accuracy inspection prevents installation failure from stripping or cross-threading
▪ Machined sealing surface for reliable sealing with O-rings/bonded washers, reducing leakage risk
▪ Structural strength meets system working pressure requirements, maintaining stable hydraulic and air circuit pressure
▪ Anti-rust surface treatment resists outdoor mud and dust, reducing corrosion seizure
▪ Can be stocked together with hydraulic hoses, connectors, pipe clamps, and related pipeline accessories

FAQ 

Q：When does an elbow need replacement?
A: Replace when the sealing surface or threads are damaged, O-ring aging causes leakage, the elbow is corroded and seized unable to disassemble or tighten, or threads are stripped. Continued use may cause persistent hydraulic oil or compressed air leakage and system pressure drop.

Q：Is leakage at the elbow always caused by the elbow itself?
A: Not necessarily. Check whether the O-ring or bonded washer is aged/damaged, the pipe end is intact, and the elbow is tightened to specified torque first. Inspect the elbow body after confirming seals and pipe ends are normal.

Q：What to note during elbow installation?
A: Confirm thread specification, bend angle, and sealing type match the original. Tighten to specified torque to avoid over-tightening damage to threads or sealing surface. Clean pipeline interfaces before installation to prevent contaminants from entering the system.

Q：How to maintain the elbow daily?
A: Periodically inspect for oil or air leakage traces. During pipeline maintenance, check O-ring condition and replace promptly if aged. Keep the elbow surface clean to prevent long-term mud adhesion causing corrosion.
