It integrates seamlessly with standard AC pipelines via the 3/8-24UNF Male thread—an industry-common fitting that eliminates the need for adapters. The dual pressure protection mechanism is critical: triggering HP OFF at 3.14MPa to prevent compressor overheating and pipeline rupture, and LP OFF at 0.196MPa to avoid damage from refrigerant deficiency. Optimized for R-134a, it’s ideal for modern vehicle maintenance and aftermarket replacement, while customization options cater to special vehicle configurations.

Superior Quality & Reliability Engineering

Quality is core to the SHK-241-003, with design and testing adhering to strict automotive industry standards. The switch features a corrosion-resistant brass housing that withstands extreme temperatures (-40℃ to 85℃) and engine compartment vibration, ensuring durability in harsh operating environments.

Its precision-calibrated pressure sensors offer a tolerance of ±0.05MPa, guaranteeing accurate response without false triggers. High-quality sealing materials compatible with R-134a ensure leak-proof performance, while the durable contact design passes over 100,000 pressure cycle tests—validating long-term reliability for the vehicle’s lifecycle.

Every unit undergoes rigorous quality inspections, including pressure threshold verification, leak testing, and temperature endurance trials. Batch production records and customization specs are fully traceable, backed by an 18-month warranty, providing confidence for users and partners.

Application

The SHK-241-003 AC pressure switch applies to AC systems of all vehicle models, including passenger cars, SUVs, light trucks, and buses. It’s widely used in aftermarket replacement, vehicle assembly, and automotive maintenance scenarios. By real-time monitoring R-134a refrigerant pressure, it triggers shutdown at 3.14MPa (high pressure) and 0.196MPa (low pressure) to protect compressors and pipelines. The 3/8-24UNF Male thread enables direct installation, with customizable versions adapting to special layouts and working conditions.
