• Fiber reinforced composite rubber material, good medium temperature resistance, stable for cooled compressed air transmission, not easy to soften or deform.
• Integrated forming design of pipe body, flange and bell mouth, reduce assembly joints and lower air leakage risk.
• Excellent vibration absorption performance, buffer vibration transferred from engine and air cooler, reduce fatigue cracking risk.
• Wear-resistant outer rubber layer, effectively resist gravel scratch and dust erosion inside engine compartment, extend service life.
• OEM contour and installation hole layout, fully consistent with original pipeline, no on-site modification required, shorten maintenance time.
• Good structural toughness, keep intact under pressure fluctuation caused by frequent acceleration and deceleration.
• When matched with supporting clamps and gaskets, sealing performance is reliable to prevent compressed air escaping.
• Batch air tightness inspection before delivery, every pipe passed pressure test to avoid sudden air leakage on construction

FAQ 

Q：What signs mean the air cooler outlet pipe needs replacement?
A：Visible cracks on pipe surface, bulging, air leakage at flange or bell mouth joint, pipe hardening or softening, obvious deformation under working pressure.

Q：What should be noted during air cooler outlet pipe installation?
A：Clean the connecting surface before installation; align flange holes and tighten bolts evenly; install hose clamps properly at bell mouth; avoid sharp bending or twisting the pipe. Keep pipe away from high-temperature exhaust parts and sharp metal edges.

Q：What are common causes of air cooler outlet pipe damage?
A：Long-term aging; vibration fatigue from engine; friction with surrounding metal components; improper installation with excessive bending; over-tightened bolts causing flange crack.

Q：Can leaking air cooler outlet pipe be repaired and reused?
A：Not recommended. Adhesive repair or wrapping will fail quickly under pressure fluctuation. Replace new pipe directly once cracks or air leakage appear.

Q：How to inspect air cooler outlet pipe during daily maintenance?
A：Check pipe surface for cracks, swelling and air leakage before heavy-load operation. Inspect tightness of flange bolts and hose clamps. Focus inspection on flange and bending areas, these parts are most vulnerable to aging and leakage.

Q：What failures will a failed air cooler outlet pipe cause?
A：Damaged pipe causes compressed air leakage, reduces air intake volume, lowers engine power. Serious leakage will lead to black smoke, increased fuel consumption and insufficient power under heavy load.

Q：Can this air cooler outlet pipe fit other loader models?
A：This air cooler outlet pipe is custom made for ZL50G/ZL50GL. Length, inner diameter and flange hole layout are exclusive. It cannot be fitted directly on other models without modification. Wrong replacement will cause poor sealing and air leakage.
