R134a QC-LA and QC-HA Fitting Set

Discover the R134a QC-LA and QC-HA Fitting Set (Reference: 080607), an essential technical solution for all professionals and knowledgeable enthusiasts working on automotive air conditioning systems. This complete kit ensures quick, secure and perfectly sealed connections on R134a refrigerant circuits.

Applications and technical advantages

These quick-connect fittings are specially designed to meet the strict requirements of automotive air conditioning maintenance. The QC-LA (Quick Connect Low Side) fitting connects to the low-pressure side of the circuit, while the QC-HA (Quick Connect High Side) adapts to the high-pressure side. This differentiation ensures optimal safety and prevents any connection errors.

Perfect for R134a refrigerant recharge operations, circuit evacuation, leak testing or operating pressure control. These fittings are also suitable for preventive maintenance operations and fault diagnosis on light vehicles, commercial vehicles and certain heavy vehicles equipped with R134a systems.

Design and technical compatibility

Manufactured according to the most demanding industrial standards, these fittings feature robust construction in corrosion-resistant metal alloy that withstands temperature variations. The integrated O-rings ensure perfect sealing even under the high service pressures characteristic of R134a systems.

The quick-lock system allows instant connection and disconnection without refrigerant loss, thus complying with current environmental regulations. The integrated anti-backflow design prevents any fluid reflux during operations, ensuring operator safety and system integrity.

Compatible with all brands of air conditioning maintenance equipment: automatic charging stations, analog or digital manifolds, vacuum pumps, leak detectors and pressure measurement devices.

Usage and installation procedures

Installing these fittings requires no specific tools. Simply locate the service ports on the vehicle: the low-pressure port (generally located on the suction line between the evaporator and compressor) and the high-pressure port (positioned between the compressor and condenser).

Before any connection, check the condition of the service ports and clean them if necessary. Push the fitting firmly until the locking click that confirms secure connection. For disconnection, activate the release mechanism while pulling the fitting.

These fittings withstand repeated thermal cycles and maintain their sealing properties over numerous uses. Minimal maintenance consists of regularly cleaning the contact surfaces and checking the condition of the O-rings, replaceable in case of wear.
