Brass Barbed Hosetail Straight Connector — Reliable Joins for Air, Water, Fuel & Gas Lines
Leaking hose joints are a frustrating and potentially dangerous problem for mechanics, plumbers, and DIY enthusiasts alike. Whether you're routing fuel lines in an engine bay, connecting air hoses in a workshop, or plumbing water lines in a garden irrigation system, a secure, leak-free connection is non-negotiable. These brass barbed hosetail straight connectors are built for exactly that — giving hobbyists, tradespeople, and small-shop operators a dependable solution that installs in seconds.
Each connector is a single-piece straight joiner machined from solid brass. The size notation follows the format Outer Diameter × Barb Diameter (e.g., 6mm-4mm means a 6mm (≈1/4") body with a 4mm (≈5/32") barb). Available sizes range from 6mm-4mm up to 20mm-10mm, covering a wide range of hose inner diameters. Order in quantities of 1, 2, 3, 5, 8, 10, 15, or 20 pieces to match your project needs.
Typical use cases include automotive fuel and coolant line repairs, pneumatic air hose connections in workshops, garden irrigation and water transfer systems, and small-engine gas line routing — all scenarios where a compact, corrosion-resistant brass barbed hose joiner outperforms plastic alternatives.
ℹ️ Compatibility: Barb diameter fits standard metric hoses. Match the second number in the size (e.g., 4mm in "6mm-4mm") to your hose's inner diameter (ID). For pressurized lines, always secure with a hose clamp.
✅ Key Features of These Brass Barbed Hosetail Straight Connectors
-
🔩Solid Brass Construction — Machined from brass for durability, corrosion resistance, and reliable performance in water, air, fuel, and gas line applications.
-
🔗Straight Joiner Design — Inline barbed hosetail connector joins two hose ends in a straight run, ideal for extending or repairing hose lines without bends.
-
📐Wide Size Range — Available from 6mm-4mm up to 20mm-10mm, covering common metric hose inner diameters for versatile use across automotive, plumbing, and pneumatic applications.
-
🛡️Barbed Grip Profile — The ribbed barb design creates a friction-lock seal that resists pull-out; pair with a hose clamp for pressurized air, water, or fuel lines.
-
⚙️Multi-Fluid Compatible — Suitable for use with water, compressed air, fuel (petrol/diesel), and gas lines — a single fitting type that works across multiple systems in your workshop or vehicle.
-
📦Flexible Quantity Options — Order 1 to 20 pieces per SKU so you can stock up for ongoing maintenance or grab just what you need for a single repair job.

❓ Frequently Asked Questions
How do I choose the right size barbed hosetail connector?
Match the barb diameter (the second number in the size, e.g., 4mm in "6mm-4mm") to your hose's inner diameter (ID). The first number is the outer body diameter of the fitting. For example, a 6mm-4mm fitting suits a hose with a 4mm (≈5/32") inner bore. When in doubt, measure your hose ID with calipers before ordering. A barb that is slightly larger than the hose ID will create a tighter seal.
What pressure rating do these brass barbed fittings typically handle?
Brass barbed hosetail connectors of this type generally handle working pressures up to approximately 150 PSI (≈10 bar) for water and air applications when used with a properly rated hose and clamp. Actual ratings depend on hose material, clamp type, and operating temperature. Contact us to confirm suitability for your specific application.
Can these fittings be used outdoors or in wet environments?
Brass offers good corrosion resistance and is generally suitable for outdoor, wet, and humid environments including garden irrigation, outdoor air lines, and vehicle engine bays. For highly corrosive environments (e.g., saltwater or strong chemical exposure), additional protection or alternative materials may be advisable.
Are these fittings compatible with standard metric hoses?
Yes. The barb diameters are sized in metric (mm) and are designed to fit standard metric hoses. The barbed profile creates a friction-lock seal. For pressurized applications, always secure with a hose clamp rated for your working pressure.
What fluids are these connectors compatible with?
These brass straight connectors are typically compatible with water, compressed air, fuel (petrol/diesel), and gas lines. Compatibility also depends on the hose material used. Always verify chemical compatibility with your specific fluid and hose before installation, particularly for fuel and gas applications.
Do I need a hose clamp with these fittings?
For low-pressure or gravity-fed water applications, the barb alone may hold adequately. For pressurized air, water, fuel, or gas lines, we strongly recommend securing the hose with a stainless steel hose clamp to prevent blow-off and ensure a leak-free connection.
How many pieces come in each order?
You can choose from 1, 2, 3, 5, 8, 10, 15, or 20 pieces per order using the Quantity(PCS) selector above. Buying in larger quantities reduces the per-unit cost — ideal for stocking your workshop or completing multi-point installations.
