FREIGHTLINER COLUMBIA 120 YEAR 2005 NORMALLY CLOSED LOW AIR PRESSURE SWITCH WITH.125-27 NTP

This replacement low air pressure switch is engineered for Freightliner Columbia 120 and compatible heavy-duty truck models requiring reliable cruise cut-off system operation. The normally closed switch activates at 70 PSI, providing critical air pressure monitoring for pneumatic brake systems and related applications where precise pressure regulation is essential. The switch features a 1/8-27 NPT threaded connection with integrated sealant provisions for secure, leak-proof installation in standard air brake configurations. The blade connector design enables straightforward plug-and-play connectivity, minimizing installation time and reducing potential connection errors in the field. This industrial-grade component measures 1.97 inches in total length, fitting within standard mounting spaces on Freightliner Columbia trucks and comparable chassis. Built to withstand the demanding conditions of commercial vehicle operation, this pressure switch delivers consistent performance across fluctuating air system pressures. The normally closed design ensures safe system defaults during idle or shutdown conditions, with the switch opening when air pressure drops below the 70 PSI threshold to trigger appropriate brake or engine management responses. This component is ideal for fleet maintenance operations, OEM replacements, and service shops specializing in Freightliner heavy-duty trucks. Proper installation requires verification of air system pressure specifications and compatibility with your specific vehicle model. Always consult your vehicle documentation or contact technical support to confirm fitment before purchase, as applications may vary across model years and configurations.
