Pack of 1 Duracool 12a Can and 1 Low-Pressure R134a Charging Hose

Duracool 12a + R134a Hose Pack (Reference: DC0051) is the complete solution for all professionals and environmentally minded private users who want to recharge their car air conditioning effectively. This innovative pack combines a 170 g can of ecological Duracool 12a refrigerant gas with a charging hose designed specifically for R134a systems, offering a sustainable alternative to traditional gases.

Benefits and use cases

This pack is aimed mainly at garages, car mechanics, refrigeration engineers and private users with a passion for mechanics who want to service their own vehicle air conditioning. Duracool 12a is perfectly suited to replacing R12, R134a and 1234yf in car air conditioning circuits, offering equivalent performance while respecting the environment.

Using this pack makes it possible to achieve substantial savings: a single 170 g can of Duracool 12a can substitute 484 g of HFC-R134a, 513 g of CFC-R12 or 340 g of HFO 1234yf. This superior efficiency considerably reduces maintenance costs while lowering the carbon footprint of the work.

The hose supplied turns this pack into a self-contained service kit, ideal for visits to customers, emergency call-outs or simply to equip your workshop with a versatile, reliable tool.

Technical features and innovation

Duracool 12a is a natural hydrocarbon-based refrigerant gas, entirely free of any greenhouse effect and of any impact on the ozone layer. This innovative composition makes it a leading ecological alternative that meets the new environmental requirements of the automotive sector.

Its universal compatibility is a major advantage: Duracool 12a works just as well with mineral as with synthetic air conditioning oils, removing any risk of incompatibility and simplifying maintenance procedures. This versatility allows it to be used on a wide range of vehicles, from older models to the most recent.

The R134a charging hose features top-quality components: crimped brass connectors for a perfect seal, a precision pressure gauge for optimal pressure control, and a robust design able to withstand intensive use. Its optimised length makes it easy to reach the service ports even in cramped engine compartments.

Installation and use

Using this pack requires following strict safety procedures. Before any work, check that the engine is switched off and has cooled down. Locate the low-pressure service port of the air conditioning circuit, usually identified by a blue or black cap.

Connect the hose to the service port, screwing it firmly but without forcing. The pressure gauge lets you check the system pressure before injecting. A pressure that is too high may indicate a fault that calls for a thorough diagnosis.

When injecting Duracool 12a, respect the recommended quantities according to the vehicle specifications. The can must be held upright and at room temperature to optimise the transfer. Keep watching the pressure gauge continuously to avoid overcharging the circuit.

After use, purge the hose and store the equipment in a dry place, away from extreme temperatures. Check the condition of the seals and connectors regularly to keep the system reliable.

Tips, synergies and expert advice

To get the most from your work, complete this pack with diagnostic tools such as an electronic leak detector or cartridges of refrigerant oil with UV tracer. These accessories make it possible to pinpoint the source of losses and carry out lasting repairs.

A professional tip is to warm the can slightly in a lukewarm water bath (never above 40°C) before use. This technique improves the fluidity of the gas and speeds up the charging process, which is particularly useful when working in cold weather.

Beware of common mistakes: never inject gas into a circuit under excessive pressure, do not mix different types of refrigerant, and always purge the air from the hose before connecting. These precautions avoid contamination and protect the integrity of the circuit.

In summer, plan ahead by building up a sufficient stock, as demand for air conditioning recharges is particularly high. Duracool 12a keeps perfectly under good storage conditions, allowing supplies to be managed efficiently.
