Do I need any tools to connect these fittings?

No tools are required. The luer lock thread is designed for hand-tightening. Simply push the barb into your tubing and twist the luer collar onto the mating port until snug.

Luer Lock Hose Barb Connector — Secure Male & Female Thread Fitting for Fluid Transfer

Whether you're building a custom fluid transfer line, setting up a lab dispensing system, or routing tubing through tight spaces, a loose or leaking connector can derail the whole project. These luer lock hose barb fittings are designed for hobbyists, lab technicians, makers, and small-scale fluid handling professionals who need a reliable, hand-tightened connection without specialized tools.

Each fitting is a straight luer lock connector with a hose barb tail, available in both Male and Female thread types. Barb sizes range from 1.6mm (≈1/16") to 6.4mm (≈1/4"), covering the most common small-bore tubing inner diameters. Order in quantities from 1 to 200 pieces to match your project scale.

Typical use cases include peristaltic pump tubing connections, syringe-to-tubing adapters for dispensing applications, aquarium and hydroponics micro-tubing fittings, and DIY fluid routing in electronics cooling or laboratory setups — all scenarios where a luer lock hose barb fitting with a secure thread interface is the right call.

🔗 Compatibility: Follows standard luer lock interface (ISO 594 / ISO 80369 family). Male type mates with female luer ports; Female type accepts male luer tips. Barb tail fits flexible tubing with matching inner diameter.

✅ Key Features of These Luer Lock Hose Barb Fittings

🔒Threaded Luer Lock Interface — The twist-lock collar creates a more secure connection than slip-fit luer fittings, reducing the risk of accidental disconnection during fluid transfer.
📐Six Barb Sizes in One Listing — Available in 1.6mm, 2.4mm, 3.9mm, 4.8mm, 5.6mm, and 6.4mm to match a wide range of small-bore flexible tubing inner diameters without needing adapters.
⚧Male & Female Options — Choose the thread type that matches your existing port or syringe interface; both types share the same barb sizing for consistent tubing compatibility.
🛠️Tool-Free Hand Tightening — The luer lock collar is designed for finger-tightening, making installation and removal fast in lab, DIY, or field settings without wrenches or clamps.
📦Flexible Quantity Options — Order from 1 to 200 pieces per size, so you can grab a single fitting for a repair or stock up for a production run or recurring project.
💧Straight-Through Flow Path — The straight barb-to-luer geometry minimizes flow restriction, making these fittings suitable for low-to-medium flow rate fluid transfer lines where pressure drop matters.

⚠️ Size Note: Barb size refers to the inner diameter of the tubing it is designed to fit. Measure your tubing's inner bore before ordering. If you are between sizes, generally size down for a tighter, more secure barb grip.

❓ Frequently Asked Questions

How do I choose the right hose barb size for my tubing?

Match the barb diameter to your tubing's inner diameter (ID). For example, a 1.6mm (≈1/16") barb fits tubing with a 1.6mm inner bore; a 6.4mm (≈1/4") barb fits 1/4" ID tubing. When in doubt, size down slightly — a snug fit generally seals better than a loose one and reduces the chance of the tubing slipping off the barb.

What is the difference between male and female luer lock fittings?

A male luer lock has an external thread collar that twists onto a female luer port (such as a syringe barrel or female luer cap). A female luer lock has an internal thread that accepts a male luer tip. They are designed to mate together for a secure, leak-resistant connection. Choose the type that matches the port on your existing equipment.

Can these fittings handle outdoor or wet environments?

These fittings are generally suitable for wet environments and fluid contact applications. For prolonged outdoor UV exposure or chemically aggressive fluids (strong acids, solvents), confirm material compatibility with your specific fluid before use. Contact us if you need clarification on chemical resistance.

Are these compatible with standard luer lock syringes and dispensing ports?

Yes. These fittings follow the standard luer lock interface (typically ISO 594 / ISO 80369 family), so they are generally compatible with standard luer lock syringes, dispensing tips, fluid transfer ports, and peristaltic pump heads used in lab, medical-adjacent, and industrial dispensing applications.

How much pressure can these fittings handle?

Pressure ratings depend on the material, tubing type, and connection torque. In most cases, luer lock barb fittings of this type are suitable for low-to-medium pressure fluid transfer. For applications with specific pressure requirements, contact us to confirm suitability before ordering.

Do I need any tools to install these fittings?

No tools are required. The luer lock thread is designed for hand-tightening. Push the barb tail firmly into your flexible tubing, then twist the luer collar onto the mating port until snug. For a more secure barb-to-tubing seal, a small amount of tubing lubricant or a hose clamp can be used, but is typically not necessary for low-pressure applications.

Which barb size should I order for 3/32" ID tubing?

3/32" is approximately 2.4mm. Select the 2.4mm barb size for the closest match to 3/32" inner diameter tubing. Similarly: 1/16" ≈ 1.6mm, 5/32" ≈ 3.9mm, 3/16" ≈ 4.8mm, 7/32" ≈ 5.6mm, 1/4" ≈ 6.4mm.
