Sourcing 64531390070 Pressure Switches FAQs
Why is the 17kg/cm² medium pressure fan trigger critical for BMW E32/E34 models?
The E34 and E32 models rely heavily on the auxiliary cooling fan to maintain cabin comfort and engine safety. At 17kg/cm², our 64531390070 switch sends a signal to engage the fan, cooling the condenser before the system reaches the 32kg/cm² high-pressure cut-off. We calibrate every unit on an automated pressure bench to ensure this threshold is met according to German OE specifications, preventing A/C shutdowns in heavy traffic.
Can we implement private label laser marking for our 64531390070 bulk orders?
Yes. For our professional importers and European specialty wholesalers, we offer full private label services. This includes high-definition laser etching of your brand logo and the 64531390070 part number directly on the sensor housing. We also provide custom-designed bulk packaging and box art that meet the premium branding requirements of the global BMW aftermarket.
What is the standard lead time for manufacturing a wholesale order of this BMW switch?
Our lead time is fixed at 60 days. This duration is strictly necessary to fulfill our IATF 16949 quality protocols, which include multi-stage pressure cycle validation and exhaustive vacuum leak testing for the 7/16-20 UNF female threads. This ensures that every 64531390070 unit arriving at your warehouse is defect-free and ready for high-volume distribution.
Is this switch specifically optimized for R134a refrigerant?
Absolutely. The 64531390070 is designed for late-model E34/E32 systems that utilize R134a. We use premium internal seals and diaphragms that are chemically resistant to HFC R134a and modern PAG oils. This ensures that the switch will not experience signal drift or seal degradation even under the high thermal stress common in classic BMW engine bays.
Do you support mixed wholesale orders for different BMW electrical sensors?
Yes. We prioritize the flexibility required by international distributors. You can combine the 64531390070 with other BMW E34 or E30 electrical sensors to meet our 100-unit MOQ. This consolidation helps significantly reduce your per-unit logistics and shipping costs for maritime or air freight.
How do you protect the female threads and internal pins during long-distance shipping?
Each 64531390070 switch is individually sealed in a moisture-proof industrial bag. For bulk orders, we utilize reinforced export-grade cartons with internal shock-absorbing dividers to prevent the electrical pins and critical 7/16-20 UNF threads from bending or corroding. This ensures your order arrives in showroom condition ready for immediate retail.
