DANN Hydraulic is a China rotary union manufacturer specializing in compatible replacement solutions for Deublin® and other international rotary union brands. Our Deublin 1790 Series Rotary Union Replacement is developed for industrial equipment requiring reliable transfer of compressed air, hydraulic oil, vacuum, and other compatible media between stationary and rotating components.
Designed for maintenance replacement, OEM machinery, and industrial retrofit projects, our 1790 Series alternatives combine precision machining, stable sealing, flexible connection options, and engineering support for international buyers.
Important: DANN Hydraulic supplies independently manufactured compatible replacement products. Deublin® is a trademark of its respective owner. Our products are not manufactured, authorized, or endorsed by Deublin.
The 1790 Series rotary union is commonly associated with compact, low-speed rotary fluid-transfer applications.
Depending on the individual model and configuration, this type of rotary union can be used for:
Its compact construction makes the series particularly useful where installation space is limited but reliable rotary sealing is still required.
Instead of applying one specification to the entire series, DANN Hydraulic selects or develops each 1790 replacement rotary union according to the original model and actual operating conditions.
The 1790 Series is well suited to equipment requiring a relatively compact rotating connection.
Our compatible replacements are designed to provide:
This makes them suitable for industrial machinery, automation systems, rotary fixtures, and pneumatic equipment.
Different 1790 configurations may be used with different working media.
Typical applications include:
For pneumatic machinery, rotary fixtures, clamping systems, and industrial automation.
For rotating hydraulic circuits and industrial equipment requiring pressure fluid transfer.
Selected configurations can be matched to vacuum handling and rotating vacuum applications.
Media compatibility should always be confirmed according to the exact model number, seal material, pressure, temperature, and operating speed.
A rotary union must maintain a secure seal while allowing continuous relative rotation.
Our engineering process focuses on:
For replacement projects, seal selection can be adjusted according to the working medium and operating environment.
Replacement compatibility depends heavily on dimensional accuracy.
DANN Hydraulic uses precision machining processes for critical components such as:
Accurate machining helps provide stable assembly and reduces the risk of installation mismatch.
Deublin 1790 Series compatible rotary unions can be considered for equipment such as:
For unusual applications, customers can send machine information or an existing sample for engineering review.
Replacing an imported rotary union involves more than matching the series name.
Before production, our team can review:
This helps reduce incorrect selection and gives buyers a clearer basis for replacement approval.
As a direct rotary union manufacturer in China, DANN Hydraulic can support both standard replacement requirements and customized projects.
Depending on the project, we can evaluate:
Different applications may require different materials.
Our engineers can evaluate:
If the original model is unavailable or discontinued, customers may provide:
We can then evaluate a suitable replacement solution.
Our business focuses on rotary unions, rotary joints, and rotating fluid-transfer components, rather than supplying unrelated general industrial parts.
This allows our team to better understand practical issues such as:
We supply compatible replacement solutions for applications originally using international rotary union brands, including Deublin and other imported industrial rotary joints.
This experience is particularly useful for:
Depending on product configuration, inspection may include:
Our objective is to provide consistent industrial replacement products rather than simply reproducing an external appearance.
For technical products such as rotary unions, correct selection is often more important than selecting the lowest price.
Our team can communicate with customers based on actual operating parameters and help evaluate whether a standard or customized replacement is more suitable.
