Rotary Unions for Hydraulic Oil

The 1/8" single passage rotary union is designed with balanced mechanical seals for a robust and quality solution. The compact, rugged design is suitable for hydraulic applications like clutch and drive systems. 

Deublin's 1/4" rotating union for hydraulic fluid is compact but built for durability in applications like variable pitch sheaves. Seals are carbon graphite to tool steel.  

Deublin's 3/8" rotary union is ideal for small hydraulic applications. The compact design features seal materials that enhance the union's service life. 

The 1/2" Deublin rotary union is a self-supported, monoflow design. The 1205 features lubricated for life bearings for longer life, reducing downtime and maintenance for rotary union hydraulic applications.

Deublin's single passage rotary union is designed to transfer large volumes of hydraulic fluid. The 3/4" design features balanced mechanical seals to extend the life of the union and reduce unwanted maintenance

Large volumes of media, such as hydraulic fluid, are transferred to a stationary source through Deublin Rotary Unions. 

Deublin's compact hydraulic design can configured to fit your custom application. 

The Deublin AP series features balanced mechanical seals for smooth, high-speed rotation and resist early wear. Designed with double ball bearings, the high-pressure rotary union protects itself from contaminated hydraulic fluid caused by leakage. Additional venting also provides bearing protection. 

Deublin's unique tandem rotary union is a combination of two unions to prevent cross-contamination with independent sealing in each. This rotating union is suitable for several different media combinations that include hydraulic fluid.  

The Deu-plex hydraulic rotary union is designed with two 1/4" channels for low-speed applications. 

Deublin's 3/8" rotary union is ideal for small hydraulic applications. The compact design features seal materials that enhance the union's service life. 

Deublin two-channel and three-channel unions for  hydraulic media allow alternating pressurization.

Designed with four independent passages, Deublin's 1379 rotary union operates with various types of media such as hydraulic oil. A vent in between passages eliminates cross-contamination of two types of media. The four passage rotary union is best for applications like clamping and unclamping.

Deublin's 1479 rotary union operates at a higher flow rate with various types of media such as hydraulic oil. The design features widely spaced ball bearings to absorb the large side loads and reduce wear. Some applications requiring four passages are workpiece or spindle cooling. 

Low-speed rotary unions require special sealing with compounded O-Rings for longer seal life in hydraulic fluid applications. 

The best solution for low speed, hydraulic rotary union is Deublin's 17 series. The 17 series offers specially designed seals and compounded O-rings to ensure a longer life. An economical solution ensuring the rotating union's durability and efficiency. 

The D series design is that of a high-pressure swivel with the ability to handle angular movement. One application is power steering systems on earth moving equipment.  This low-speed rotating union is suitable for hydraulic oil or water. 

Deublin's Deu-plex rotating union is a precision solution ideal for hydraulic applications operating at different pressures. 

Double-acting hydraulic cylinders require Deublin's two-passage rotary unions to long life without leakage. 

Deublin's two-channel union features independent passages with closed seal technology.  Special designs prevent cross-contamination of dissimilar media, such as hydraulic fluid and water.
