When your Cummins 4BT or 6BT engine won't shut down properly, every minute of downtime costs money—whether it's a construction site waiting for your excavator or a fleet truck stuck in the yard. Many repair shops waste days replacing cheap solenoids that fail within months, or pay 30-50% more for OEM parts with 2-4 week lead times. Worse, counterfeit solenoids often cause secondary failures, turning a simple repair into a major overhaul.
Our 12V Stop Solenoid (3930658/SA-4756-12) solves these headaches with factory-direct quality you can trust. As a 10-year global supplier with 20+ engineering experts, we source exclusively from ISO-certified manufacturers and test every unit before shipment. Unlike generic parts, this solenoid matches OEM specifications for voltage tolerance and response time—critical for preventing engine damage during shutdown cycles. With 10,000+ parts in stock at our Guangzhou warehouse, we ship in 2-5 working days, so you can get equipment back online fast.
This 12V Stop Solenoid is the control center for fuel cutoff in Cummins 4BT and 6BT engines—found in excavators, bulldozers, generators, and heavy-duty trucks operating in the harshest conditions. Whether your equipment is moving earth at a mining site, loading cargo at a port, or powering tools on a construction job, this solenoid must reliably cut fuel flow when activated. A failing solenoid can lead to unplanned shutdowns, fuel waste, or even safety hazards in high-risk environments.
What makes our solenoid stand out? The copper coil is wound to precise resistance specifications (12V), ensuring consistent magnetic force to actuate the fuel shutoff valve. The plunger assembly features hardened steel construction to withstand millions of cycles without deformation. We use high-temperature seals rated for engine bay conditions, preventing oil leaks that cause solenoid burnout. Every unit undergoes 100% functional testing—including voltage drop and response time checks—to ensure it meets Cummins 4BT/6BT operating parameters. These details translate to longer service life and fewer replacements compared to budget alternatives.
Opting for a $20 "bargain" solenoid might save money upfront, but consider the hidden costs: a failed solenoid can strand a $500,000 machine for days, costing $2,000-$5,000 in lost productivity. Counterfeit parts often have 1.5x shorter lifespans, meaning you'll replace them twice as often. Our 12V Stop Solenoid, backed by ISO manufacturing standards and a 3-12 month warranty, reduces total cost of ownership by minimizing downtime and replacement frequency. It's not just a part—it's an investment in reliable equipment performance.
We've earned the trust of 120+ countries by delivering on our promises: All parts come from ISO-certified factories with strict incoming material inspections. Every solenoid undergoes pre-shipment performance testing to ensure OEM-equivalent function. Our technical team verifies part compatibility within 2 hours, so you never install the wrong component.
