FAQ

Is this orifice tube compatible with my vehicle?

Yes, the ACDelco A/C Orifice Tube matches the OEM part number 19189842, which is used in many makes and models. Verify your vehicle’s service manual or consult a professional to confirm compatibility.

Can I install the tube myself?

Installation is straightforward for anyone with basic automotive tools. Remove the old tube, ensure the system is evacuated of moisture, and install the new ACDelco tube using the factory fittings. Always follow safety guidelines and consider a professional recharge after installation.

What are the benefits of aluminum over plastic?

Aluminum provides higher tensile strength, better heat dissipation, and greater resistance to chemical degradation. This results in a longer service life and more consistent refrigerant flow compared to plastic counterparts.

Do I need to replace other components when changing the orifice tube?

While the orifice tube can be replaced independently, it is good practice to inspect related components such as the receiver‑drier and expansion valve. Replacing them together can prevent future leaks and ensure optimal system performance.

How does this part affect system performance?

The precise orifice size and high‑quality construction maintain the designed pressure drop, ensuring the A/C system delivers the intended cooling capacity and efficiency. This helps avoid over‑charging or under‑charging issues that can arise with mismatched parts.
