Product Description

SHK-133: Customizable AC Pressure Switch for All Vehicle Models

The SHK-133 is a versatile air conditioning pressure switch (with customizable specs) engineered for universal fit across all vehicle models, focused on AC system protection:
Category Item Specification
Thread Size Connection Type M12×1.5 Female (Customizable)
Operating Pressure ON Pressure 0.31MPa

OFF Pressure 0.17MPa
Compatibility Refrigerant Type R-134a
Application Vehicle Fit All Vehicle Models
In automotive AC systems, it acts as a core safeguard—activating at 0.31MPa (ON) to prevent overpressure damage and deactivating at 0.17MPa (OFF) to avoid underpressure malfunctions. The M12×1.5 female thread (with customization options) ensures seamless installation on standard AC pipelines of passenger cars, SUVs, commercial vehicles, and trucks.
R-134a compatibility aligns with modern automotive AC systems, making it a widely applicable replacement part. Its robust construction withstands extreme temperature fluctuations (-40~85℃) and automotive vibration, delivering consistent pressure control to extend AC system lifespan. Customizable parameters (e.g., thread size) cater to specialized vehicle setups.

SHK-133: Industrial-Grade Quality & Customizable Reliability

The SHK-133 adheres to automotive component standards, with quality controls balanced with customization flexibility:
  • Pressure Precision: Calibrated to ON 0.31MPa/OFF 0.17MPa (±0.02MPa tolerance) for accurate AC system protection, with customizable pressure thresholds available.

  • Durable & Customizable Construction: High-quality brass housing (corrosion-resistant) with M12×1.5 thread (or custom thread options) meets industrial sealing standards for leak-proof performance.

  • Refrigerant Compatibility: R-134a-specific seal materials ensure chemical stability, with compatibility for other refrigerants available via customization.

  • Rigorous Testing: Undergoes 500,000 cycle pressure tests, temperature endurance trials, and vibration resistance testing—customized units receive model-specific validation.

  • Traceability & Warranty: 18-month warranty; batch records and customization specs are fully traceable, meeting global automotive aftermarket requirements.


Application

The customizable SHK-133 AC pressure switch applies to all vehicle models (passenger cars, SUVs, commercial vehicles, trucks) for R-134a AC system protection. It monitors refrigerant pressure (ON 0.31MPa/OFF 0.17MPa) to prevent damage, with M12×1.5 (or custom) thread for universal/specialized installation.
