Purpose and function in the air conditioning system

The offered pipe belongs to the Air conditioning pipes, hoses and connectors group and is a component of the refrigerant flow path in the A/C system. It is responsible for the airtight connection of selected components (e.g., compressor, condenser, evaporator, or receiver-drier – depending on the specific configuration of the system in a given vehicle), which has a direct impact on:

• maintaining the correct refrigerant pressure,
• reducing air conditioning performance losses,
• maintaining system tightness and protection against moisture and contamination ingress.

Thanks to its fitment to the SLK R170 body structure, the pipe routes the refrigerant without interfering with other installations, minimizing the risk of abrasion and stress during suspension and engine operation.

Original origin and fitment for Mercedes SLK R170

The element was designed by Mercedes specifically for the geometry and pressure requirements of the air conditioning system in the SLK R170. This means:

• factory fitment to mounts and brackets in the engine bay and chassis,
• compatibility with original A/C system connectors and seals,
• no need for modifications or the use of adapters during installation.

Such a solution facilitates service work, shortens repair time, and limits the risk of leaks resulting from the incorrect selection of a replacement part.

Characteristics of the used air conditioning pipe

As a used part, the Mercedes SLK R170 Air Conditioning Pipe Refrigerant A/C Hose Line represents a reasonable compromise between repair costs and maintaining the manufacturer's original specifications. In practice, this means that:

• the original geometry and length of the pipe are preserved,
• the connectors are matched to the factory system ports,
• standard service procedures (vacuuming, refilling, leak testing) are possible.

Before installation, it is recommended to perform a professional leak test of the entire system and replace the seals at connection points to fully utilize the potential of the part and limit the risk of subsequent leaks.

Technical support and part selection by numbers

The pipe belongs to a group of elements where precise matching to the specific body version and air conditioning system configuration is crucial. In case of doubt, it is worth using catalog numbers or vehicle data to verify compatibility with your SLK R170. This approach facilitates workshop work and reduces the risk of selecting the wrong section of the A/C installation.
