Sourcing 6L3419D594AA A/C Pressure Switch FAQs
Why is the 35 kg/cm² cut-off point critical for F-150 applications?
Ford’s modern truck platforms use high-capacity condensers that operate at elevated pressures compared to older sedans. The 35 kg/cm² threshold on our 6L3419D594AA ensures that the compressor is only disabled at the absolute limit of safety, preventing "nuisance tripping" while providing ironclad protection against system over-pressurization during heavy towing or extreme heat.
How does your product ensure the long-term reliability required by Top 100 wholesalers?
We utilize reinforced internal diaphragm technology that specifically resists the pressure pulsations common in large displacement Ford compressors. Every unit is subjected to IATF 16949 compliant stress testing, ensuring that your clients receive a component that lasts the entire service life of the vehicle, reducing the high labor costs associated with repeated A/C repairs.
Does this switch integrate with the PCM logic for fan and clutch control?
Absolutely. The electrical resistance and switching speed of our 6L3419D594AA are perfectly matched to Ford’s Powertrain Control Module (PCM) parameters. This ensures that the ECU receives accurate signals to engage cooling fans and cycle the clutch, restoring original HVAC efficiency and fuel economy for your professional customers.
What private label and branding services do you offer for large importers?
For our strategic B2B partners, we offer a full-service private label program. This includes precision laser etching of your brand logo and the 6L3419D594AA OE number on the sensor housing, as well as customized industrial packaging. This allows you to build brand equity in the high-volume Ford truck aftermarket.
What is the lead time for container-load wholesale orders?
We maintain a streamlined 60-day manufacturing cycle. This period includes the precision calibration of the 35 kg/cm² OFF and 21 kg/cm² ON points, followed by a 100 percent vacuum leak test. Our commitment to this timeline ensures that your distribution network never experiences stockouts on this high-demand F-Series SKU.
Is the fitting compatible with original liquid line ports without adapters?
Yes. Our 6L3419D594AA is designed as a direct "drop-in" replacement. The M10-P1.25 threads are machined to zero-tolerance specifications and include a pre-installed, high-grade HNBR seal. This guarantees a leak-free installation on Ford, Lincoln, and Mercury vehicles, providing the "plug-and-play" reliability that professional technicians expect.
