Plastic Barbed Hose Fitting with Male Thread — Straight Connector for Air, Fuel & Water

Match the barb diameter to your hose's inner diameter (ID). For example, a hose with a 6.4mm (≈1/4") ID typically pairs with a 6.4mm barb. When in doubt, measure your hose ID with calipers and select the closest barb size listed in the variant options. A slightly snug fit is generally better than a loose one for leak resistance.

These fittings generally follow NPT (National Pipe Taper) or BSP (British Standard Pipe) thread conventions depending on the size. If thread standard compatibility is critical for your application, please contact us before ordering to confirm the specific thread type for your chosen size.

The plastic construction is generally resistant to moisture and mild corrosion, making these fittings suitable for sheltered outdoor use such as garden irrigation systems. For prolonged direct UV exposure or harsh chemical environments, we recommend verifying material compatibility. These are not rated for high-pressure outdoor hydraulic systems.

Working pressure varies by size and application. These fittings are typically suited for low-to-medium pressure applications — in most cases, this includes air lines for hobby pneumatics, garden water lines, and small engine fuel systems. For exact pressure ratings for your specific size, please contact us to confirm before use in pressurized systems.

These fittings are generally suitable for light fuel line applications such as lawn mowers, generators, and small garden equipment. For aggressive fuels, high-temperature fuel systems, or automotive applications, verify chemical compatibility with the plastic material before use. When in doubt, contact us to confirm suitability.

Wrap the male threads with PTFE tape (2–3 wraps) before threading into the port — this creates a leak-free seal. Hand-tighten first, then snug with a wrench (avoid overtightening plastic threads). Push the hose firmly over the barb until it seats past the first ridge. For added security in pressurized applications, secure the hose with a hose clamp over the barbed section.

Each variant is listed as Thread Size — Barb Diameter. For example, "1/4" — 6.4mm" means a 1/4" male thread with a 6.4mm (≈1/4") barb shank. Thread sizes range from 1/8" to 3/4", and barb diameters range from 2.8mm to 25mm. Match the thread size to your port and the barb diameter to your hose inner diameter.
