Conditions of use:Rotation speed ≤3000 Rpm Temperature ≤150℃ Pressure ≤1.5 Mpa Medium: air, water, oil

High-pressure rotary joint

Product size: from 1/4 inch to 1-1/2 inch

Structural features:Made of 304 stainless steel material to meet different customer needs and usage environments. The rotary seal has better performance, better wear resistance, high temperature resistance, longer service life and a wide range of uses.

Conditions of use:Rotation speed ≤150 Rpm Temperature ≤150℃ Pressure ≤40 Mpa Medium: air, water, oil

Product size: from DN10 to DN50

Structural features:Single and dual channel designs. Brass housing, stainless steel rotor. Long service life, replacement for Deublin 55/155 series rotary joint.

Conditions of use:Rotation speed ≤3500 Rpm Temperature ≤120℃ Pressure ≤50 bar Medium: air, water, oil

55/57-355/357 rotary joint

Hydraulic right angle rotary joint

Product size: from 1/4 inch to 2 inch

Structural features:suitable for high-pressure occasions with low rotation or swing frequency. It is small in size and easy to install. It is made of stainless steel and supported by oil-free composite bearings. Generally used in hydraulic pipelines at normal temperature.

Conditions of use:Rotation speed ≤0~30 Rpm Temperature ≤-200~120℃ Pressure ≤1~25 Mpa Medium: hot water, steam, nitrogen, organic solvents, carbon oxides, cryogenic liquids

HK type rotary joint

Product size: from 1 inch to 4 inch

Structural features:Use external springs to make the media flow more smoothly. Reduce user costs. It has the advantages of small size, light weight, more reliable sealing and long working life.

Conditions of use:Rotation speed ≤200~3000 Rpm Temperature ≤120℃ Pressure ≤1.8 Mpa Medium: hot water, steam, oil，coolant, compressed air

Steel mill series rotary joint

Product size: 59h6

Structural features:Specially used for continuous casting machine equipment. High temperature resistance, wear resistance, unique inverted built-in sealing type, more convenient for disassembly, assembly and maintenance of joints.

Conditions of use:Rotation speed ≤60 Rpm Temperature ≤230℃ Pressure ≤1.2 Mpa Medium: coolant water

Frequently asked questions

What is a rotary joint/union?

A rotary joint/union (or swivel joint) is a device used to transfer fluid under pressure or vacuum from a stationary inlet to a rotating outlet, preserving and isolating the fluid connection.

What is your process for a custom rotary union solution?

First, contact us to Get Started. Our team will reach out to you to start learning more about your project's technical and delivery requirements. We will consider all aspects of your application and work together to develop the best solution.

How do I choose a rotary joint/union?

Proper selection of a rotary union solution requires details about your application's operating parameters including pressure, speed, media type(s), number of flow passages (channels), and connection size / type. A good place to start your search is with our Standard Rotary Unions. If you are confident that a custom / modified solution is most likely required or need assistance in your selection, contact us to Get Started. Our experts are here for you.

Do you offer compatible options for replacing another manufacturer's fluid rotary union?

Yes, we can cross reference other manufacturer's fluid rotary unions to find an equivalent solution. Contact us to Get Started.

Do you offer custom rotary unions?

Yes, it's what we do best! We can meet your exact fluid rotary union requirements from modifying our standard products to complete, custom design and manufacturing. For more information see Custom Solutions.

What is the life expectancy of a rotary union?

The life expectancy of a rotary union varies widely depending on many application variables: media type, pressure, rotational speed, duty cycle, temperature, and more. If you need further assistance contact a member of our Sales Support Team.
