Coupler Plug Hose Barb

Infinity Quick Coupler Plug: Hose Barb (Industrial M-Style)

The Direct Link for Custom Hose Fabrication

Streamline your air lines and eliminate unnecessary leak points with the Infinity Hose Barb Coupler Plug. This one-piece connector combines a standard Industrial Interchange plug directly with a hose barb tail, allowing you to connect a rubber air hose straight into your quick coupler system without the need for intermediate threaded adapters.

Whether you are repairing a damaged hose end, shortening a line for better management, or fabricating custom “whip hoses” for your tools, this plug provides a secure, low-profile, and durable solution.

Key Features & Benefits

• Integrated One-Piece Design: Stop screwing a threaded plug into a separate threaded barb. This integrated unit eliminates that connection entirely, reducing the weight of the hose end and removing a common source of air leaks.
• Secure Hose Retention: Features sharp, precision-machined barbs that grip the inside of the hose wall. When paired with a proper hose clamp (worm gear or O-clip), it ensures the hose will not blow off, even under heavy pressure or pulling tension.
• Industrial Standard (M-Style): Machined to the MIL-C-4109 (Industrial Interchange) specification. This ensures compatibility with all standard Infinity Industrial couplers, as well as M-Style couplers from other manufacturers.
• Case-Hardened Steel: Like all Infinity plugs, the plug section is case-hardened to resist the wear and grooving caused by the locking balls of the coupler. This ensures a long service life and prevents damage to the coupler’s internal seals.
• High-Flow Bore: The internal passage is drilled for maximum diameter, minimizing airflow restriction and ensuring your tool gets the volume it needs.

Technical Specifications

• Plug Profile: 1/4″ Industrial Interchange (Type M)
• Connection: Hose Barb (Insert)
• Available Barb Sizes:
  • 1/4″ ID Hose
  • 3/8″ ID Hose
  • 1/2″ ID Hose
• Material: Case-Hardened Steel (Zinc/Nickel Plated)
• Pressure Rating: Up to 300 PSI (Dependent on hose and clamp rating)
• Temperature Range: -40°F to +250°F

Ideal Applications

• Hose Repair: Quickly fix a burst hose by cutting off the bad section and inserting a new barb plug.
• Whip Hoses: Creating short, flexible “whips” (2-5 ft) to go between a heavy tool and the main air line, reducing wrist strain for the operator.
• Bulk Hose Installs: Terminating bulk hose from a reel without needing crimping equipment.

Installation Note

Safety First: A hose barb must be secured with a hose clamp or crimp ferrule. Never rely on the friction of the barb alone to hold compressed air pressure.
