Brass Hose Tail Fittings – Barb Connector Straight Tee Y-Shape 90° Elbow Cross | Air Water Pipe Adapter

Match the barb diameter to your hose inner diameter (ID). For example, a 10mm barb fits a hose with a 10mm ID (approximately 3/8"). Use calipers to measure the inside of your hose if you're unsure. A snug fit is generally preferred — the barb should require light force to insert. If your hose ID falls between sizes, typically size up for easier installation or size down for a tighter grip.

Straight — Joins two hoses end-to-end in a straight line. Ideal for extending a hose run or repairing a cut line. Tee — Splits or merges flow at a 90° branch (T-shape). Common in irrigation manifolds. Y-Shape — Similar to a Tee but with an angled branch, allowing smoother flow splitting. 90° Elbow — Redirects a single hose run by 90°, useful in tight spaces. Cross — Connects four hose ports in a plus (+) configuration for multi-directional distribution.

Brass generally offers good corrosion resistance for outdoor and moist environments, making it a common choice for garden irrigation and outdoor water systems. For prolonged saltwater exposure or highly acidic or alkaline environments, additional sealing or a stainless steel alternative is typically recommended.

Brass hose barb fittings are typically rated for low-to-medium pressure applications. The actual working pressure depends on the hose material, wall thickness, clamp type, and operating temperature. For high-pressure pneumatic or hydraulic systems, always verify compatibility with your hose and clamp manufacturer's specifications before installation.

Yes. The barb diameters listed — 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, and 19mm — correspond to standard metric hose inner diameters. Always measure your hose ID before ordering. These fittings are push-on barb style only and are not designed for NPT or BSP threaded connections.

For most pressurized applications — including air lines, water systems, and fuel lines — using a hose clamp over the barb connection is strongly recommended to prevent blow-off and leaks under pressure. For very low-pressure or gravity-fed systems, the barb grip alone may be sufficient. Hose clamps are not included with this product.

Brass hose barb fittings are generally compatible with water, air, light oils, and many fuels. They are not typically recommended for strong acids, alkalis, or chlorinated fluids, which can degrade brass over time. If you're unsure about fluid compatibility for your specific application, contact us to confirm before ordering.
