Danfoss 7765028 Adapter Set

The Danfoss 7765028 is a professional-grade Rotolock to brazed adapter set designed to facilitate seamless connections between HVACR compressors and system piping. This kit includes two 1-3/4" Rotolock adapters and one 1-1/4" Rotolock adapter, engineered to transition to ODF solder connections (7/8” and 1-3/8”). These adapters are essential for retrofitting or replacing Danfoss Performer compressors where a secure, leak-free mechanical joint is required before transitioning to copper lines. The precision-machined threads and heavy-duty construction ensure a high-pressure seal, reducing the risk of refrigerant leaks during thermal expansion cycles. By utilizing these brazed adapter kits, technicians can maintain the integrity of the refrigeration system while ensuring compatibility with standard brazing techniques. These components are critical for field service applications involving commercial HVAC equipment, providing the necessary bridge between specialized compressor ports and standard 1-1/8" or 1-3/8" tubing sizes.

Key Benefits for Technicians:

• Durable Brass Construction: High-tolerance machining prevents galling and ensures a repeatable seal on Rotolock valves.
• Optimized Flow Path: Designed to minimize pressure drop through the discharge and suction ports.
• Field Versatility: Eliminates the need for custom-fabricated fittings when installing Danfoss refrigeration components.
• Reliable Sealing: Compatible with standard teflon gaskets to ensure a gas-tight fit under high-vibration conditions.

Common Questions & Technical Support:

What compressor series are these adapters compatible with?
These adapters are typically used with Danfoss SZ, SM, and SY series compressors that feature 1-1/4" and 1-3/4" Rotolock fittings.

Do I need to remove the internal seals before brazing?
Yes, always remove any teflon seals or gaskets from the adapter before applying heat to the solder connection to prevent melting or seal failure.

Can these be used with R-410A and R-404A systems?
Yes, these adapters are rated for high-pressure HFC refrigerants and standard refrigeration oils used in modern HVACR systems.
