Brass Elbow Barb Hose Connector — Reliable 90° Routing for Air, Gas & Fuel Lines
Routing flexible hose around corners in tight engine bays, pneumatic panels, or fuel systems is a constant challenge — a straight connector just won't do. Whether you're a mechanic, fabricator, or hands-on DIYer, a leaky or ill-fitting elbow can mean downtime, wasted materials, or worse, a safety hazard. These brass 90° elbow barb hose tail connectors are built to solve that problem cleanly and reliably.
Each piece is machined from solid brass and features a 90-degree elbow profile with a ribbed barb hose tail on each end. Available in sizes from 4mm to 19mm (≈5/32" to 3/4") barb OD, they fit a wide range of flexible hose inner diameters. You can order 1, 2, or 5 pieces per set to match your project quantity — no need to buy in bulk when you only need one.
Typical use cases include routing air lines in compressor setups, connecting fuel hoses in small engines and carbureted vehicles, directing gas tubing in laboratory or workshop equipment, and managing coolant or vacuum lines in automotive applications — all situations where a brass elbow barb fitting for air and fuel lines makes the difference between a clean install and a messy workaround.
🔵 Compatibility: Fits flexible hoses with inner diameters (ID) of 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, or 19mm. Suitable for air, gas, fuel, coolant, and vacuum lines. Always match barb OD to hose ID for a secure fit.
⚠️ Before ordering: Measure your hose's inner diameter (ID) with calipers. The barb OD listed in the size options should match your hose ID. If you're unsure, contact us to confirm before purchase.
✅ Key Features of These Brass Elbow Barb Hose Connectors
-
🔩 Solid Brass Construction — Machined from brass for natural corrosion resistance, making these fittings suitable for air, gas, and fuel line applications in both indoor and outdoor environments.
-
↩️ True 90° Elbow Profile — The right-angle design allows clean directional changes in tight spaces without kinking the hose — ideal for engine bays, pneumatic panels, and compact plumbing runs.
-
🔒 Ribbed Barb Grip — The stepped barb teeth grip the hose interior firmly, reducing the risk of pull-out. Pair with a hose clamp for a leak-resistant connection under pressure.
-
📐 Wide Size Range (4mm–19mm) — Eight barb sizes cover the most common flexible hose inner diameters used in automotive, workshop, and laboratory settings — from small vacuum lines to larger fuel hoses.
-
🛒 Flexible Quantity Options — Choose 1, 2, or 5 pieces per order so you get exactly what your project needs without overstocking. Useful for repairs, prototyping, or small-batch builds.
-
⚙️ No-Thread Barb Design — The hose tail end inserts directly into flexible hose — no threading tools required. Installation is straightforward and compatible with standard worm-drive or ear-style hose clamps.

❓ Frequently Asked Questions
How do I choose the right barb size for my hose?
Match the barb OD (outer diameter) to your hose's inner diameter (ID). For example, a 6mm (≈1/4") barb fits a hose with a 6mm ID. Measure your hose ID with calipers before ordering — don't rely on the hose's outer diameter. A snug fit prevents leaks without requiring excessive clamp force.
What pressure rating do these brass elbow fittings typically handle?
Brass barb fittings generally handle working pressures in the range of 100–150 PSI for air and water applications, though the actual rating depends on hose material, clamp type, and operating temperature. For high-pressure or safety-critical systems, please contact us to confirm suitability before purchase.
Are these fittings suitable for outdoor or corrosive environments?
Brass offers good natural corrosion resistance and is generally suitable for outdoor and mildly corrosive environments. It is not recommended for prolonged exposure to saltwater or highly acidic media. For harsh marine or chemical environments, stainless steel fittings may be a more appropriate choice.
Can I use these connectors for fuel lines?
Yes. Brass is generally compatible with gasoline, diesel, and many common fuels. Always verify compatibility with your specific fuel type and ensure the hose material is also fuel-rated. Use an appropriate hose clamp to secure the barb connection and prevent pull-out under pressure.
Do I need a hose clamp with these barb fittings?
For very low-pressure or static applications, a push-fit connection may hold adequately. However, for air, gas, or fuel lines — especially under any working pressure — we strongly recommend using a worm-drive or ear-style hose clamp over the hose to ensure a leak-free, secure connection.
What thread or connection standard do these fittings use?
These are barb-style (hose tail) fittings — they insert directly into flexible hose and do not use threaded connections on the barb end. The barb OD matches the listed size (4mm through 19mm). If you need a threaded-to-barb adapter, please contact us to confirm compatibility with your system.
Which hose materials work with these brass elbow connectors?
These fittings are typically compatible with flexible hoses made from PVC, rubber, silicone, polyurethane, and similar materials. Rigid or semi-rigid tubing is not suitable for barb-style fittings. Always confirm the hose ID matches the barb OD before installation to ensure a proper seal.
