Product Description

SHK-124: Universal AC Pressure Switch for All Vehicle Models

The SHK-124 is a dedicated air conditioning pressure switch engineered for universal fit across all vehicle models, with core specs tailored to AC system protection:

Category	Item	Specification
Thread Size	Connection Type	7/16-20UNF Female
Operating Pressure	ON Pressure	0.31MPa
	OFF Pressure	0.17MPa
Compatibility	Refrigerant Type	R-12
Application	Vehicle Fit	All Vehicle Models

In automotive AC systems, it acts as a critical safeguard—activating at 0.31MPa (ON) to prevent overpressure damage and deactivating at 0.17MPa (OFF) to avoid underpressure malfunctions. The 7/16-20UNF female thread ensures seamless installation on standard AC pipelines of all vehicle makes and models, from compact cars to commercial vehicles.

R-12 refrigerant compatibility aligns with legacy and select modern AC systems, making it a versatile replacement part. Its rugged design withstands extreme temperature fluctuations (-40~80℃) and vibration, delivering consistent pressure control to extend AC system lifespan and reduce maintenance needs.

SHK-124: Industrial-Grade Quality for Automotive AC Reliability

The SHK-124 adheres to strict automotive component standards, with quality controls focused on precision and durability:

Pressure Control Precision: Calibrated to ON 0.31MPa/OFF 0.17MPa with ±0.02MPa tolerance, eliminating false triggers and ensuring accurate AC system protection.
Durable Construction: High-quality brass housing with corrosion-resistant plating resists refrigerant corrosion, while 7/16-20UNF thread meets industrial standards for leak-proof sealing.
Refrigerant Compatibility: R-12-specific seal materials ensure chemical stability and prevent leakage, matching the fluid requirements of targeted AC systems.
Rigorous Testing: Undergoes 500,000 cycle pressure tests, high/low-temperature endurance trials, and automotive-grade vibration resistance testing to ensure reliability.
Traceability & Warranty: 18-month warranty, with batch production records and performance test data fully traceable, meeting global automotive aftermarket standards.

Application

The SHK-124 AC pressure switch applies to all vehicle models (passenger cars, SUVs, commercial vehicles, trucks) for air conditioning system protection. It monitors R-12 refrigerant pressure, activating at 0.31MPa and deactivating at 0.17MPa to prevent overpressure damage and underpressure failures, with 7/16-20UNF thread for universal installation.
