NPT Male Straight Barb Hose Connector — PE Plastic, Air & Water, 1/8" to 3/4"

Match the barb diameter to your hose's inner diameter (ID). For example, a 1/4" (6.4mm) barb fits a hose with a 1/4" ID. When in doubt, measure the inside of your hose with calipers — a snug fit prevents leaks without requiring excessive force to push the hose on.

These connectors are available in NPT male thread sizes from 1/8" to 3/4", paired with barb diameters from 4.8mm (≈3/16") to 14mm (≈9/16"). Select your size and pack quantity from the variant options above.

PE (polyethylene) plastic is generally resistant to moisture and mild UV exposure, making it suitable for outdoor irrigation and garden watering setups. For prolonged direct sunlight or high-UV environments, additional UV protection is typically recommended.

PE plastic barb connectors are generally rated for low-to-medium pressure applications — typically up to 60–100 PSI depending on temperature and hose condition. For high-pressure pneumatic or hydraulic lines, a metal fitting is typically recommended.

Yes. These use standard NPT (National Pipe Taper) male threads, which are compatible with NPT female ports found on pumps, valves, tanks, and manifolds commonly used in the US. Use PTFE thread tape for a leak-free seal on the threaded end.

For low-pressure water or air lines, the barb's ribbed profile typically holds the hose securely without clamps. For higher-pressure or vibration-prone applications, a hose clamp over the barb is generally recommended for added security.

PE plastic is compatible with water, air, and most mild aqueous solutions. It is generally not recommended for use with fuels, solvents, or aggressive chemicals. Confirm fluid compatibility with PE before use in specialty applications.
