239-6687 Air Hose — Cat 325D 329D

This is an Air Hose, a flexible conduit designed to safely transport air under pressure within various machine systems, such as the braking or pneumatic systems. Manufactured from durable materials, it resists cracking and abrasion, ensuring a reliable air supply, unlike a worn hose that may develop leaks or burst. Operators may notice issues with brake performance, air leaks, or system pressure loss when this hose fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Visible cracks, swelling, or hardening of the hose material are the first indicators of a potential failure. If ignored, these weaknesses can lead to air leaks, resulting in reduced system pressure and impaired functionality, such as poor braking performance. A sudden hose rupture under pressure can cause sudden system failure and potential safety hazards.

Installation Tip

Ensure all connection points are thoroughly cleaned and free of any old sealant or debris before attaching the new hose. Do not twist or kink the hose during installation, as this can restrict airflow and compromise its integrity.

Service Note

When replacing an air hose, inspect all adjacent hoses, fittings, and air tanks for signs of wear, corrosion, or leaks.
