The High/Low-pressure Line, air conditioning (30013607) transports refrigerant through the air conditioning system under pressure. Replacing it with a Porza-quality pipe restores cooling efficiency and long-term system reliability.
A high/low-pressure line for air conditioning is a hose or pipe that carries refrigerant between components of the AC system. The high-pressure line transports compressed refrigerant from the compressor, while the low-pressure line returns it to the compressor after cooling.
Key specifications include length, diameter, material (such as aluminum or reinforced hose), pressure rating, connection type, and compatibility with the AC system. They must withstand high pressure, temperature changes, and refrigerant exposure.
Replacement is necessary when the line is leaking, cracked, corroded, or damaged. Common symptoms include loss of cooling performance, visible refrigerant leaks, or AC system failure.
Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.
Porza provides high-quality air conditioning components with fast delivery across Europe and options for online ordering or in-store pickup.
If the fit guarantee is selected, compatibility is verified before shipping. If the product does not fit, it can be returned according to the return policy.
