Product Specifications: - High Pressure (Red) Connector: - Head: R134A 16mm - Middle: 1/4 SAE internal thread and 1/4 SAE external thread - Bottom: R1234YF 17mm - Low Pressure (Blue) Connector: - Head: R134A 13mm - Middle: 1/4 SAE internal thread and 1/4 SAE external thread - Bottom: R1234YF 14mm Product Installation Location: - The high-pressure quick connector is typically installed on the high-pressure line close to the compressor's output. This is where the refrigerant's pressure increases before it enters the condenser. Product Usage: - Enables fast and easy connection and disconnection of air conditioning system pipelines. Ideal for maintenance personnel to perform refrigerant charging, discharging, or recovery without tools. Scope of Use: - Compatible with AC charging of R1234YF/R12 to R134A automotive air conditioning systems. Suitable for R1234yf refrigerant, AC manifold pressure gauges, and diagnostic inspection, recovery, and evacuation tasks. Product Features: - Instant locking and releasing mechanism allows for quick, tool-free connections and disconnections of refrigerant pipelines, enhancing maintenance efficiency. Product Composition: - Includes: - High pressure connector: 1 piece - Low pressure connector: 1 piece - Air conditioning valve core wrench: 1 piece Use Scenarios: 1. Quickly charge or recover refrigerant during routine AC maintenance without the need for additional tools. 2. Effectively diagnose pressure issues in automotive air conditioning systems using the connectors with AC manifold gauges. 3. Simplify the process of switching between different refrigerants when servicing multiple vehicles.
