Application and design
The Sunair BC-54759-06-06K is a 45-degree O-ring bulkhead fitting kit for heavy-duty A/C refrigerant hose connections. Engineered as a male insert bulkhead, it creates a secure pass-through at the panel while maintaining a serviceable O-ring seal. Its #6-to-#6 configuration and industry-standard 5/8-18 thread streamline integration with common hose ends and bulkhead plates across mobile HVAC platforms. Steel construction provides the mechanical strength needed for fleet, bus, and off-highway environments. Classified under VMRS 001-001-227, this fitting supports reliable, repeatable sealing to help maintain charge and uptime.

Compatibility and serviceability
The connector style is Burgaclip, enabling drop-in compatibility with Burgaflex assemblies and simplifying field service. The 45-degree angle improves hose routing clearance at the bulkhead, reducing bend stress and abrasion risk in tight compartments. With End 1 Type 6 and End 2 Type 6, technicians can standardize on #6 hose inventory and fittings. Country of origin is United States to support sourcing requirements. For cross-reference, it interchanges with Burgaflex BC547590606K and Kysor 2660060. Choose BC-54759-06-06K when you need a durable, leak-resistant bulkhead connection that installs cleanly, holds torque, and stands up to vibration in demanding HVAC service.
