Danfoss 068U7000 Repair kit

The Danfoss 068U7000 Repair Kit, also known as the TUA Mini-Mizer Kit, is a specialized OEM solution for servicing Danfoss TUA and TUAE thermostatic expansion valves. Designed as a direct replacement for the obsolete 000MMK-U and 000MMK-U00 models, this kit allows contractors to restore precise superheat control without a full valve replacement. Engineered with sweat minimizer technology, it supports reliable field maintenance on systems utilizing R22, R134a, and R404A refrigerants. This industrial-grade package includes high-quality TXV spare parts that ensure leak-free performance and optimal refrigerant flow across a broad temperature range from -40°F to +50°F. By utilizing genuine Danfoss expansion valve parts, technicians maintain the integrity of the stainless steel valve body and ensure compatibility with the existing power head and sensing bulb setup, extending the operational life of commercial refrigeration and air conditioning equipment.

Common Questions

Is the 068U7000 compatible with newer R407C systems?
Yes, Danfoss TUA/TUAE valves serviced with this kit are often used in R407C applications; however, always verify the specific orifice and valve body rating for your system's required capacity.

Can I use this kit to replace parts in a flare-connection valve?
This specific kit (068U7000) is designated as a Sweat Minimizer kit. For flare or mixed connection types, verify your valve's type designation as the internal gaskets and filters may differ from the 068U7001 flare/sweat variant.

Do I need to replace the entire power head when using this repair kit?
No, this kit is designed to service the internal components. Since Danfoss TUA/TUAE valves feature a laser-welded, non-replaceable power head, this repair kit is the primary method for restoring valve function without replacing the entire body.
