Sourcing 90GG19D566AA A/C Pressure Switch FAQs

Why is the 18.5 kg/cm² Medium Pressure (MP) logic critical for classic Ford HVAC?

Classic Ford systems rely heavily on timely fan engagement to prevent heat soak in the condenser. The 18.5 kg/cm² ON point ensures the auxiliary fan activates before head pressure reaches dangerous levels, preserving the compressor's mechanical life. Every unit undergoes 100 percent automated pressure bench testing to ensure zero-drift calibration for these safety-critical points.

Can we implement private label laser marking for our bulk orders?

Yes. For our professional importers and Top 100 global wholesalers we provide high-definition laser etching. We can mark your brand logo and the 90GG19D566AA OE number directly on the sensor body to help you build brand authority in the Ford classic car aftermarket.

What is the standard manufacturing lead time for wholesale orders?

Our fixed lead time is 60 days. This duration is required for the precision assembly of the trinary diaphragm stack and exhaustive IATF 16949 quality verification. This ensures the long-term reliability expected by international procurement networks.

Is this switch compatible with R134a retrofitted classic cars?

Absolutely. While originally designed for R12 systems, we use high-grade internal seals and diaphragms that are chemically resistant to both R12 and modern HFC R134a/PAG oil environments. This prevents seal degradation in vehicles updated to modern environmental standards.

Do you support mixed wholesale orders for Ford and other European car sensors?

Yes. We offer flexibility for our international distributors. You can combine the 90GG19D566AA with other Ford, Jaguar, or BMW pressure sensors to meet our 100-unit MOQ to effectively optimize your logistics and inventory turnover.

How do you protect the 7/16-20 UNF threads and terminals during shipping?

Each unit is individually sealed in a moisture-proof industrial bag with a protective internal plug for the threads. For bulk export we use reinforced export-grade cartons with internal shock-absorbing dividers to ensure the electrical terminals and precision threads arrive in perfect condition.
