Applicable Scenarios

It connects pneumatic components of XCMG ZL50G and ZL50GL wheel loader and is fixed on frame air circuit brackets, widely used in quarry, aggregate yard and earthwork construction sites.

▪ OEM pipe length, bending shape and connector specification match original parts for direct installation without pipe reworking
▪ Pressure resistance matches rated working pressure of air circuit, resisting bulging and burst under air pressure
▪ Oil and mud resistant material avoids hardening and cracking under long-term vibration for longer service life
▪ Moderate flexibility absorbs frame vibration and reduces joint loosening and leakage risk
▪ High-precision sealing surface of matched connectors achieves good pressure retention together with new gaskets
▪ Simple layout and easy disassembly help maintenance workers quickly find leakage points
▪ Compatible with air tank, brake cylinder, combination valve and other pneumatic fittings of the same model
▪ Factory air tightness sampling test eliminates defective pipes with pinhole and hidden leakage to stabilize air pressure

FAQ 

Q：Can I continue working if fine cracks appear on the pipe surface?
A：It is not recommended. Cracks will expand under air pressure and vibration and may cause sudden leakage and insufficient brake air supply. Replace it promptly.

Q：Can I only replace the gasket if leakage only occurs at the joint?
A：If the pipe end is intact without aging and deformation, only the gasket can be replaced. Replace the whole pipe if the port is damaged.

Q：What should be noticed during installation?
A：Do not twist or stretch the pipe, reserve buffer clearance. Avoid over-clamping. Tighten threads evenly and test leakage after assembly.

Q：What harm will hydraulic oil cause to the air pipe?
A：Hydraulic oil erodes the pipe, causes swelling and accelerates aging. Keep away from oil leakage and replace swollen pipes.

Q：Does low air pressure mean this pipe is leaking?
A：Not necessarily. Check air compressor, combination valve, air tank and other joints first.

Q：How to store spare air pipe?
A：Store in dry and shaded place, avoid sunlight, heavy load and sharp bend, protect connectors from dirt.

Q：Can a dented air pipe still be used?
A：Dent reduces flow area and slows air charging. Replace it if the dent is serious.
