Applicable Scenarios

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

▪ OEM interface dimensions and thread specifications 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 washers/ferrules, reducing air and oil leakage risk
▪ Structural strength meets system working pressure requirements, maintaining stable air and hydraulic pressure
▪ Anti-rust surface treatment resists outdoor mud and dust, reducing corrosion seizure
▪ Can be stocked together with air pipes, hydraulic hoses, elbows, pipe clamps, and related pipeline accessories

FAQ 

Q：When does a connector need replacement?
A: Replace when the sealing surface or threads are damaged, seal aging causes air/oil leakage, the fitting is corroded and seized unable to disassemble or tighten, or threads are stripped. Continued use may cause persistent media leakage and system pressure drop.

Q：Is leakage at the connector always caused by the connector itself?
A: Not necessarily. Check whether the sealing washer or ferrule is aged/damaged, the hose end or steel pipe interface is intact, and the fitting is tightened to specified torque first. Inspect the connector body after confirming seals and pipe ends are normal.

Q：What to note during connector installation?
A: Confirm thread specification 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 connector daily?
A: Periodically inspect for air or oil leakage traces. During pipeline maintenance, check seal condition and replace promptly if aged. Keep the fitting surface clean to prevent long-term mud adhesion causing corrosion.
