description

This 252109472 brake cylinder air hose is matched for parking brake air circuit of XCMG ZL50G and ZL50GL wheel loader. It adopts multi-layer composite weather-resistant rubber hose with built-in reinforcing braid layer and pre-assembled threaded connectors on both ends. Compressed air is delivered from hand brake valve to brake cylinder through this hose to realize parking brake lock and release. Hose length, connector specification and bending radius follow OEM drawings to avoid excessive bending and tension after installation. It can directly replace old damaged hoses, compatible with original valves, cylinders and brackets without re-routing pipelines. Every hose passes air pressure and bending fatigue test. It is oil-resistant and mud-resistant, suitable for bumpy and wide-temperature working conditions, preventing brake malfunction caused by air leakage.

advantage

▪ OEM length, connector specification and bending angle match original parts for direct installation
▪ Reinforced braid provides high pressure resistance against bulging and bursting
▪ Oil and aging resistant rubber resists oil splash and weather erosion
▪ Galvanized fittings with precise sealing surface prevent rust and joint leakage
▪ Optimized layout avoids sharp bending and guarantees smooth air flow
▪ Good flexibility absorbs frame vibration and reduces loose joint leakage
▪ Compatible with hand brake valve, brake cylinder, air reservoir and pipe clamps
▪ Pressure inspection screens defective hoses to ensure stable air transmission

FAQ 

Q：Can the hose with minor surface cracks keep working?
A：Stop operation. Cracks will expand and cause air leakage and rolling risk, replace immediately.

Q：How to deal with leaking connector?
A：Check sealing washer and retighten. Replace whole hose if thread is damaged or hose root cracks.

Q：What is the hazard of hardened aging hose?
A：Loss of flexibility leads to crack and leakage under vibration, causing slow parking brake release.

Q：Can I reuse old fittings with cut hose?
A：Not recommended. Reassembled fittings have poor sealing and leakage risk.

Q：How to store spare air hose?
A：Store in cool shaded place, avoid heavy bending and long-term contact with oil and water.

Q：Is slow brake release caused by this hose?
A：Check air tank and valve first. Check whether the hose is flattened or blocked.

Q：How often to inspect under heavy load?
A：Visual check before each shift, look for bulges, cracks and joint leakage.
