Key Features

Dual-Passage Design (H-Type Structure)

Supports simultaneous flow of different media or supply and return lines, improving efficiency and saving space.

High-Pressure & High-Speed Capable

Handles up to 20 bar pressure and 3000 RPM, depending on model and media.

Long-Lasting Sealing System

Equipped with advanced carbon graphite, ceramic, or silicon carbide seals to prevent leaks under tough operating conditions.

Self-Supporting or Housing-Mounted Options

Offers flexible mounting types to fit various machine configurations.

Corrosion-Resistant Body

Made with anodized aluminum, brass, or stainless steel for long-term performance in harsh environments.

Our seals are on CNC machine tools and special grinding machines. The finished, mirror-like surface makes the seal more reliable, and high-precision rolling bearings are also used to make it rotate smoothly.

Applicaiton

The H Type Rotary Union Joint is engineered for dual-flow applications, making it ideal for industrial systems that require simultaneous media supply and return, such as cooling/heating loops, hydraulic circuits, and spray systems.

FAQ

Q1: What is the difference between an H-type and a standard rotary union?

A: The H type has a dual-flow design, allowing simultaneous inlet and outlet media flow, often used for cooling and return circuits.

Q2: Can I use this rotary union for high-temperature steam?

A: Yes. We offer high-temperature models with silicon carbide seals and stainless steel bodies for steam use.

Q3: Do you offer installation accessories or mounting brackets?

A: Yes. We can supply brackets, adapters, and flexible hoses upon request.

Q4: How can I choose the correct size and configuration?

A: Send us your application details (media, pressure, speed, connection type), and our engineers will recommend the best-fit model.

Q5: Is sample testing available?

A: Yes. We support small-quantity trial orders and offer samples for testing.
