Detailed Product Description

This A/C refrigerant discharge and suction hose assembly combines aluminum and rubber components to withstand the pressures and temperatures typical in automotive HVAC systems. It is designed for use with R134a refrigerant, the standard for many late-model vehicles. The assembly includes multiple green o-rings (part numbers 24608, 24612, and 24615) to ensure leak-free connections at both discharge and suction ends, which feature female UNF o-ring fittings. The integrated muffler helps minimize operational noise, contributing to a quieter cabin environment. Note that this assembly does not include fittings, brackets, or a switch service port, so those components must be sourced separately if required.

  • Resolving refrigerant leaks caused by degraded o-rings or hose material
  • Restoring proper refrigerant flow to improve A/C system efficiency

  • Ensure compatibility with Chevrolet S10, S10 Blazer, S15, S15 Jimmy, and Sonoma models before installation
  • Inspect and replace all o-rings included with the assembly to prevent leaks
  • Use proper torque specifications for UNF female o-ring fittings to avoid damage
  • Verify that the muffler is correctly positioned to reduce noise effectively
