90217 Pressure Switch 110psi ON 145psi Off – 1/8" NPT Male Air Compressor Pressure Switch, Heavy Duty 30A，Replace 90217 for Air Horn Train Systems

Compatible with air compressors, pneumatic systems, and hydraulic systems: Suitable for air compressors, vehicle pneumatic systems, hydraulic systems, air horns, train whistles, and other equipment requiring automatic air pressure control. The 1/8-inch NPT threaded interface offers broad compatibility Higher pressure range for large pneumatic tools: Compared to 90-120PSI switches, this 110-145PSI pressure switch provides a higher control pressure range. Suitable for pneumatic tools, truck air brake systems, and industrial pneumatic equipment requiring higher operating air pressure Solve insufficient pressure in high-pressure systems: Some pneumatic equipment requires operating air pressures above 100PSI to operate properly. Low-pressure switches cannot provide sufficient pressure to the air tank; this switch's 145PSI stop pressure ensures a sufficient high-pressure air source in the tank Suitable for truck air brakes and heavy-duty pneumatic systems: Heavy-duty truck air brake systems and industrial pneumatic equipment typically require operating air pressures of 120-130PSI. This pressure switch controls the air compressor to start at 110 PSI and stop at 145 PSI, providing ample pressure reserve for the system Replacement for 90217 and other compatible models: Directly replaces 90217 and other pressure switches with 1/8-inch NPT threads and a control range of 110-145 PSI. Before purchasing, please ensure that the original switch's interface thread and control parameters are consistent with this product

• Applicable Model: Fit for air compressors, automotive electrical systems, hydraulic systems, and more, Replace 90217
• Precise 110PSI Start, 145PSI Stop: This 90217 pressure switch has a preset control range of 110PSI start and 145PSI stop. It monitors system air pressure in real time, automatically starting the air compressor when the pressure drops to 110PSI and automatically stopping when it rises to 145PSI, maintaining a stable air supply pressure
• 30A High Current Carrying Capacity: The switch contacts are rated for 30A, compatible with most household and commercial air compressor motors. Extends switch lifespan
• Quick Replacement of Old and Damaged Switches: Directly replace the faulty 90217 pressure switch on the original equipment. Remove the old switch, wrap it with Teflon tape, screw in the new switch, and connect the wires to complete the replacement; no adjustment of control parameters is required
• Simple and Quick Installation: The replacement steps are: disconnect the power, remove the old switch, wrap Teflon tape around the threads, screw in the new switch and tighten, connect the wires, and test start/stop
