• Description:

  This is a genuine Ford A/C Pressure Sensor O-Ring, part number 1W1Z-19E889-HB. It is a precision elastomer sealing ring that seats in a machined groove to keep refrigerant, oil, or coolant contained at a joint while resisting heat, pressure, and chemical exposure. A correctly sized ring preserves the factory seal and prevents the seepage that worn or incorrectly specified rings allow. This part applies to Edge/Explorer/F-150/Fusion/Escape + Lincoln/Mercury (A/C refrigerant pressure sensor / line junction O-ring seal, multi-position, multi-vehicle), covering the 2003 to 2025 model years where the original equipment part was used; always confirm fitment against your specific year, model, and engine before ordering. As a genuine Ford part it is built to the original engineering specification and held to factory quality control, so it fits and performs like the component it replaces without the guesswork of aftermarket substitutes. This is a single-use component and should be replaced with a new part whenever the joint or connection it serves is disturbed, since reusing it can compromise sealing or clamp load and lead to leaks or loosening over time. Installing the correct Ford part number the first time avoids return trips and the fit and reliability problems that come with incorrect or lower-grade replacements, and it keeps the vehicle's systems working the way the factory intended. Order by part number 1W1Z-19E889-HB to be sure you receive this exact genuine Ford component.
