Pipe fron Filter to Union
$91.66
- Type: High-pressure liquid refrigerant line within the Air Conditioning (A/C) system.
- Function: Transports purified, high-pressure, liquid refrigerant from the outlet of the receiver/drier (the “filter”) directly to the inlet of the expansion valve (the “union”). This is the final high-pressure line before the refrigerant enters the cabin’s evaporator.
- Location: Typically runs from the receiver/drier (often mounted near the condenser or wheel well) towards the firewall where the expansion valve is usually located.
- Material: Primarily constructed from rigid, durable aluminum alloy tubing, often incorporating flexible, high-pressure reinforced synthetic rubber hose sections to manage routing and absorb vibrations.
- Connections: Features precise, sealed fittings (e.g., O-ring connections, specialized couplers) at both ends, engineered to maintain a leak-proof seal under the continuous high pressures of the liquid line.
- Durability: Designed to withstand the high pressures (typically 150-300 psi or 10-20 bar), varying temperatures, and engine vibrations inherent in the A/C system.
- Compatibility: Precisely manufactured to fit the specific routing, lengths, and fitting types required by the Maserati 4200’s A/C system and engine bay layout.
The A.C. Pipe – From Filter to Union, identified by Maserati Part Number 66063200, is a critical, high-pressure conduit in your Maserati 4200 GT’s air conditioning system. This specific line plays an essential role by meticulously delivering the fully filtered and dehydrated liquid refrigerant from the receiver/drier (the “filter”) to the threshold of the cabin’s cooling mechanism – the expansion valve (the “union”).
Following its journey through the condenser (where it turns into a high-pressure liquid) and then the receiver/drier (where moisture and contaminants are removed), the refrigerant is now in its optimal state for cooling. This pipe then carries that clean, high-pressure liquid to the expansion valve. The expansion valve is where the refrigerant undergoes a sudden pressure drop, causing it to rapidly cool and turn into a misty vapor, ready to absorb heat from the cabin air inside the evaporator.
Constructed primarily from robust aluminum alloy tubing, this high-pressure line is built to endure the considerable pressures and temperature variations of the A/C system’s liquid side. It often integrates sections of reinforced flexible hose to accommodate movement and dampen vibrations, particularly in areas susceptible to engine motion. Precision-engineered fittings with durable O-rings at each connection point are paramount to prevent any refrigerant leakage, which is a common and detrimental issue for A/C system performance.
Damage to this A.C. pipe, whether due to corrosion, fatigue from vibrations, or external impact, will inevitably lead to refrigerant leaks. A loss of refrigerant directly translates to a significant reduction or complete failure of the A/C system’s cooling capability, making driving in hot and humid conditions, such as those prevalent in Douala, highly uncomfortable. For your Maserati 4200, ensuring the integrity and proper function of this vital A.C. pipe with a genuine Maserati Part Number 66063200 or a high-quality OEM-equivalent replacement is crucial. This guarantees the efficient and reliable operation of your climate control system, allowing you to consistently enjoy the cool and luxurious cabin environment of your Italian grand tourer.
