Applicable Scenarios

It connects pneumatic components on 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 radian and connector specification match original parts for direct installation without reworking
▪ High-pressure resistant material matches system working pressure, resisting bulging and burst under air pressure
▪ Oil, mud and aging resistant material prevents hardening and cracking under long-time vibration
▪ Moderate flexibility absorbs frame vibration and reduces loosening risk of joints
▪ Matching connectors with stable sealing performance and good pressure retention with gaskets
▪ Lightweight and flexible for easy layout, disassembly and leakage troubleshooting
▪ Compatible with air tank, combination valve, cut-off cylinder and other pneumatic parts of the same model
▪ Air tightness sampling inspection screens defective pipes with pinhole and hidden leakage to stabilize air pressure

FAQ 

Q：Can the pipe with tiny surface cracks keep working?
A：It is not recommended. Cracks will expand under vibration and air pressure, which may cause air leakage and insufficient brake air supply. Replace it in time.

Q：Can I only replace the gasket instead of the whole pipe if the joint leaks?
A：If the pipe body is intact and the port is not cracked, only the gasket can be replaced. Replace the whole pipe if the port is aged or cracked.

Q：Will hydraulic oil damage the air pipe?
A：Long-term contact with hydraulic oil causes swelling and aging. Keep away from oil leakage and replace swollen pipes.

Q：Is low air pressure always caused by this pipe?
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 pressure and sharp bend, protect connectors from dirt.

Q：What is the hazard of dented air pipe?
A：Dent reduces flow area, slows charging speed and increases compressor load. Replace severely deformed pipes.

Q：Does low temperature damage air pipe easily?
A：Low temperature reduces flexibility and makes it easy to crack under impact. Check pneumatic pipes frequently in winter.
