4-Channel Liquid Swivel Joint G1/8 Stainless Steel Rotary Union

4-Channel Liquid Swivel Joint – G1/8 Thread | Stainless Steel & Aluminum Alloy

Engineered for demanding fluid transfer applications, this 4-Channel Liquid Swivel Joint features a G1/8 thread connection and delivers outstanding sealing performance across all four independent flow channels. Whether used in industrial machinery, rotary tables, hydraulic systems, or automated equipment, this swivel joint allows continuous 360° rotation while maintaining a secure, leak-free fluid path.

Constructed from premium stainless steel (with aluminum alloy options available), this rotary union is built to withstand corrosion, pressure fluctuations, and heavy-duty operational cycles — making it a reliable choice for professional and industrial environments.

Made in China.

Key Features

• 4 Independent Channels: Simultaneously route four separate fluid lines through a single compact rotating joint — ideal for complex multi-circuit systems.
• G1/8 Thread Connection: Standard BSP thread for easy integration with existing pipework, fittings, and hydraulic/pneumatic systems.
• Superior Sealing Performance: Precision-engineered seals minimize leakage and maintain consistent pressure integrity across all channels during full 360° rotation.
• Stainless Steel Construction: High-grade stainless steel body offers excellent corrosion resistance, durability, and longevity in wet or chemically exposed environments.
• Aluminum Alloy Option: Lightweight aluminum alloy variant available for applications where weight savings are a priority without sacrificing strength.
• Compact & Versatile Design: Space-saving form factor fits a wide range of industrial and automated machinery setups.
• No High-Concern Chemicals: Safe material composition with no restricted or high-concern chemical substances.

Frequently Asked Questions

Q: What types of fluids are compatible with this 4-channel swivel joint?

A: This swivel joint is designed for general liquid and fluid media including water, coolant, light oils, and other compatible hydraulic fluids. The stainless steel construction provides excellent corrosion resistance for a wide range of fluid types. Always verify compatibility with specific chemicals or aggressive media before use.

Q: What is the G1/8 thread standard used on this swivel joint?

A: G1/8 refers to a British Standard Pipe (BSP) parallel thread with a nominal diameter of 1/8 inch. This is a widely used thread standard in industrial fluid and pneumatic systems, making this swivel joint easy to integrate into most European and international machinery setups.

Q: Can this swivel joint handle continuous rotation under pressure?

A: Yes. The swivel joint is engineered for continuous 360° rotation while maintaining a reliable, leak-free seal across all four channels simultaneously, making it suitable for rotating machinery, turntables, and automated equipment operating under sustained fluid pressure.

Q: What is the difference between the stainless steel and aluminum alloy versions?

A: The stainless steel version offers superior corrosion resistance and durability in harsh or wet environments. The aluminum alloy version is a lighter-weight alternative suitable for applications where reducing overall system weight is important, while still providing good strength and sealing performance.
