70R4346S 45° Male O-Ring Refrigerant Steel Fitting – #6 Fitting x #6 Hose

The 70R4346S 45° male O-ring fitting is designed to provide a secure and leak-resistant refrigerant connection in compact or angled installations. Because it uses a steel body and an O-ring sealing surface, it delivers reliable performance in high-pressure mobile A/C systems.

Additionally, this fitting is commonly cross-referenced across major OEM platforms. As a result, it is frequently found in Mack and Volvo HVAC systems, as well as other heavy-duty truck and equipment applications. The 45-degree bend helps reduce hose strain while improving routing flexibility.

For best results, always install with compatible barrier refrigerant hose and follow standard HVAC installation practices.
