Kleinn Sealed Tank Mount Pressure Switch/ 1/4In M NPT/ 100 PSI On/ 130 PSI Off - 2131

WHY CHOOSE THE MODEL 2131?

• PRECISION-TUNED CALIBRATION: Engineered to kick in at 100 PSI and cut out at 130 PSI. This ensures your tank is always primed for massive air horn blasts.
• BATTLE-READY SEALED DESIGN: The fully sealed housing slams the door on moisture, dust, and road debris, making it the only choice for rugged under-vehicle mounting.
• ERROR-PROOF WIRING: With non-polarized leads, there is no "wrong" way to wire it—meaning faster installs and zero risk of wiring-induced failures.
• TOTAL SYSTEM FORTIFICATION: Designed to command a 12V ignition signal to a 40-amp relay, shielding your compressor from electrical burnout and maximizing its lifespan.

THE VERDICT: Engineered as the definitive 130 PSI control component for light-duty configurations, the Model 2131 eliminates pressure regulation guesswork while offering durable, weather-sealed structural protection.

⚠️ Pro Installation Tip: Relay Protection

SHIELD YOUR INVESTMENT. For maximum reliability and long-term performance, power this switch via an ignition source of 10+ amps. This MUST be used in conjunction with a 30/40 amp relay (like the Kleinn Model 340) to shield internal contacts from high-amperage surges during compressor startup. Proper isolation ensures consistent switching and hammers down on premature wear.

⚠️ Critical Maintenance Tip: Fight Corrosion

DON'T LET MOISTURE KILL YOUR SYSTEM. Pressure switches are high-performance wear items. To maximize longevity, use the Kleinn Snorkel Air Filter Relocation Kit included with all of our air compressors. By routing your air intake inside the vehicle cab, you significantly reduce moisture intake, stop internal tank corrosion dead, and effectively double the service life of your pressure switch.
