New Oil Pressure Switch SM-2C-20F 23520025 1/8" NPT 20PSI for Nason

Exact 20PSI Trigger: Snap-action mechanism activates within ±0.5PSI tolerance, ensuring real-time cutoff for low-oil scenarios . Heavy-Duty Diaphragm: Nitrile-coated elastomer resists oil degradation and cyclic fatigue, enduring 250+ PSI operational loads . Burst-Proof Safety: Reinforced brass housing withstands 750PSI surge pressures, preventing rupture in hydraulic shocks Tool-Free Calibration: Thumbwheel adjuster fine-tunes set points visually; color-coded dial (red=alert zone) simplifies field optimization . Thermal Resilience: -40°C~120°C operational range maintains switch integrity in arctic cold or engine bay heat, eliminating false triggers .
