Keep cold air moving and refrigerant routed correctly with the Four Seasons A/C Refrigerant Discharge / Suction Hose Assembly 55571. Built with an application-specific design, it's a direct-fit replacement for the 1987 Mercedes-Benz 300D and 300TD (both L6-3.0L), carrying refrigerant between the A/C system's high- and low-pressure sides.
- Refrigerant-compatible hose: constructed with double wall barrier hose compatible with R1234YF, R134A or R12; cataloged refrigerant type R134A.
- Aluminum and rubber construction: made from aluminum and rubber with crimp fitting connections.
- UNF O-Ring ends: both ends use a Female O-Ring, UNF O-Ring style connection.
- Seals and bracket included: ships with the gaskets, o-rings, or seals to properly complete the replacement and includes a mounting bracket; fittings and a service port are not included.
The discharge side carries high-pressure refrigerant from the compressor toward the condenser, while the suction side returns low-pressure refrigerant to the compressor. A cracked, chafed, or leaking hose is a common source of lost cooling and low refrigerant. If a failed hose assembly is the cause, this replaces it.

Frequently Asked Questions
What does this hose assembly do?
It routes refrigerant through the A/C system—the discharge side carries high-pressure refrigerant from the compressor toward the condenser, and the suction side returns low-pressure refrigerant to the compressor.
Which vehicles does it fit?
It's an application-specific replacement for the 1987 Mercedes-Benz 300D and 300TD, both with the L6-3.0L engine. See the "Vehicles it fits" section to confirm your vehicle.
What refrigerant is it compatible with?
The double wall barrier hose is compatible with R1234YF, R134A or R12; the catalog lists refrigerant type R134A.
Does it include seals and a bracket?
Yes—it ships with the gaskets, o-rings, or seals to properly complete the replacement and includes a mounting bracket. Fittings and a service port are not included.
How does it connect?
It uses crimp fitting connections with UNF O-Ring ends—both ends are a Female O-Ring style connection.
