Sourcing 80440-SM4-003 from Professional Supplier FAQs

Does this pressure switch handle the higher pressures of R-134a conversions?

Absolutely. While many older Honda systems originally used R-12, our 80440-SM4-003 is engineered with modern internal seals that are fully compatible with R-134a. This makes it an ideal component for shops performing refrigerant conversions and retrofits.

How do you guarantee the reliability of the high-pressure (30-32 kg/cm²) cut-off points?

Precision is our priority. Every switch is tested on our automated pressure-bench line where we simulate real-world HVAC cycles. We guarantee that the circuit will break exactly at the specified thresholds to prevent catastrophic system failure or hose bursts.

What customization options do you provide for large-scale B2B importers?

We offer comprehensive private label services. For bulk orders meeting our MOQ, we can provide custom-branded neutral boxes, laser-etched logos or OE numbers on the switch body, and palletized shipping configurations optimized for container sea-freight.

How does your lead time compare to original equipment manufacturers for these legacy parts?

Since these are legacy OE numbers, many original manufacturers have moved to small-batch, high-cost production. As a specialized aftermarket factory, we maintain high-volume production efficiency, typically fulfilling wholesale orders within 60 days at a significantly more competitive price point.

Can we consolidate this SKU with other Honda electrical sensors in one shipment?

Yes. Our "One-Stop Sourcing" model allows you to mix multiple SKUs—including ABS sensors, blower motor resistors, and other pressure switches—into a single wholesale order. This drastically reduces your per-unit logistics cost and simplifies inventory management.

What is your policy on defect claims for international wholesale accounts?

We stand behind our quality with a 12-month warranty. In the rare event of a functional failure, we provide a streamlined claim process where we offer replacements or credits in your next bulk shipment upon verification of the batch number and defect report.
