Danfoss 068U1033 Orifice Assembly

The Danfoss 068U1033 Orifice Assembly is a key component for contractors maintaining TUA and TUAE thermostatic expansion valves. Designed for high-reliability systems, this Size 03 replacement orifice ensures precise refrigerant flow control across a wide range of operating conditions. Engineered with stainless steel construction and high-grade bimetal connections, it facilitates clean, fast soldering without the need for wet cloths, specifically for hermetic refrigeration systems. This assembly is R404A, R22, R407C, and R134a compatible, providing a nominal capacity of approximately 1/3 to 1/2 ton depending on the refrigerant and temperature range. Using this genuine Danfoss refrigeration part guarantees the calibrated restriction necessary for stable superheat and optimized evaporator performance. Note that the 068U1033 is technically identical to the 068U103300, ensuring full cross-compatibility for field replacements. Each assembly includes a dirt protection filter to prevent orifice clogging and maintain system uptime in demanding commercial applications.

• Optimized Compatibility: Designed specifically for use with Danfoss TUA and TUAE valve bodies, ensuring seamless integration.
• Advanced Metallurgy: Features bimetal solder connections for rapid, leak-free installation into copper-to-copper lines.
• Wide Temperature Range: Rated for applications from -40°F to +50°F, making it suitable for both low-temperature and medium-temperature refrigeration.
• Debris Protection: Includes an integrated filter to capture contaminants and safeguard the precise orifice aperture.
• System Efficiency: Precise calibration maintains stable superheat, preventing liquid slugging and maximizing energy-efficient cooling.

• Can I use the 068U1033 with R410A systems? Yes, this assembly is rated for the higher pressures associated with R410A, up to a maximum working pressure of 45.5 bar.
• Is the replacement gasket included? Yes, the orifice assembly typically includes the necessary seals to ensure gastight integrity during the swap.
• How do I select the right size? Always refer to the Danfoss capacity chart; if the exact system capacity is not listed, proceed with the next larger orifice size to ensure proper flow.
