What Are Brass Hose Barbs?
Brass hose barbs (also called hose barb fittings, barbed fittings, or hose nipples) are fluid-control fittings that provide a secure, push-on connection between flexible hoses and rigid pipe or tube systems. The barbed serrations grip the interior wall of the hose when it is pushed on, creating a tight seal without the need for additional clamps in low-pressure applications. Jamnagar Brass Components manufactures a comprehensive range of brass hose barb fittings in NPT, BSP, and metric thread configurations, compliant with SAE, ASTM, and ASME standards for the US plumbing, HVAC, and fluid-handling markets.
Types of Brass Hose Barbs We Manufacture
Straight Brass Hose Barb with Male NPT Thread
The most common configuration: a single barb on one end and a male NPT thread on the other. Available in sizes 1/8″ NPT to 1″ NPT with hose ID barbs from 3/16″ to 1″. Used extensively in US water treatment, chemical dosing, and garden irrigation systems.
Elbow (90°) Brass Hose Barbs
90-degree elbow barb fittings allow hose routing in tight spaces. Available in male NPT and female NPT thread ends, used in automotive cooling systems, pool equipment, and pneumatic tool connections.
Tee Brass Hose Barbs
Three-way tee barb fittings in equal and reducing configurations. Used to branch fluid flow in manifolds, aquarium systems, laboratory tubing, and medical gas systems.
Reducing Brass Hose Barbs
Reducing barb fittings connect two hoses of different internal diameters. Common in automotive, marine, and HVAC applications where flexible hose sizes vary across the system.
Female NPT to Hose Barb Fittings
Female NPT threaded fittings with a single barb shank, for connecting flexible hose to female-threaded ports on pumps, tanks, valves, and manifolds.
Hose Barb Union Connectors
Double-barb straight connectors for joining two lengths of flexible hose in-line. Used in beverage dispensing, chemical processing, fuel systems, and pool/spa equipment.
Push-Fit Barb Fittings with Locking Nut
Enhanced barb fittings with a retaining nut or collar for use in moderate-pressure applications where pull-off resistance is required, such as compressed air, hydraulic return lines, and cooling loops.

Frequently Asked Questions (FAQ)
Q: Do brass hose barbs require hose clamps?
A: In low-pressure applications (under 30 PSI), barb fittings typically hold without clamps due to the interference fit between barb and hose ID. For higher pressures, worm-drive stainless steel clamps are recommended for maximum security.
Q: What is the difference between NPT and BSP threads on hose barbs?
A: NPT (National Pipe Taper) is the US standard with a 60° thread angle and tapered thread form. BSP (British Standard Pipe) has a 55° Whitworth thread form and is used in the UK and many other countries. They are NOT interchangeable. We supply both standards from the same facility.
Q: Are your brass hose barbs suitable for potable water?
A: Our lead-free brass (UNS C87850) hose barbs are NSF/ANSI 61 certified and compliant with California AB 1953 (max 0.25% lead) for use in potable water systems.
Q: Can you supply brass hose barbs compatible with silicone hose?
A: Yes. Our barb profiles are optimized for various hose materials including silicone, rubber, and PVC. For silicone hose, we recommend a slightly larger barb OD (typically 3–5% oversize relative to hose ID) for a secure grip.
