T-Type Barbed Hose Connector — Plastic Elbow Joiner for Air, Fuel & Water Lines

Measure the inner diameter (ID) of your hose. The barb diameter should match or be very slightly larger than the hose ID for a secure, leak-resistant fit. For example, a 6mm barb typically fits a 6mm ID hose. If you see a three-number size like "4-6-4", that means the two side ports are 4mm and the center port is 6mm — useful for connecting hoses of different sizes in a single tee joint.

Pressure ratings vary by material and diameter. Standard plastic barbed fittings generally handle low-to-medium pressures — typically up to 60–100 PSI for water and air at room temperature. PP variants are generally suitable for similar ranges. For high-pressure applications, please contact us to confirm suitability before ordering.

Plastic barbed connectors are generally resistant to moisture and mild corrosion, making them suitable for many outdoor and wet-environment applications. However, prolonged UV exposure may degrade standard plastic over time. For long-term outdoor use, we recommend securing connections with hose clamps and verifying fluid compatibility with the specific plastic grade.

Yes. The barb diameters are listed in millimeters and correspond to standard metric hose inner diameters. Common sizes like 4mm (≈5/32"), 6mm (≈1/4"), 8mm (≈5/16"), 10mm (≈3/8"), and 12mm (≈1/2") are widely used in automotive, aquarium, irrigation, and pneumatic systems. Always verify your hose's inner diameter before ordering.

Variants labeled "PP" are made from polypropylene, which offers slightly better chemical resistance and is commonly used in fuel, chemical, and food-grade fluid applications. Standard variants are typically made from a rigid plastic (nylon or ABS-type), which is well-suited for air, water, and general-purpose use. If in doubt about chemical compatibility, the PP variant is generally the safer choice.

For low-pressure applications, the barbed design typically provides a secure push-fit connection without clamps. For higher-pressure lines, vibrating environments, or fuel systems, we strongly recommend using hose clamps over each barb to prevent accidental disconnection and potential fluid leaks.

These connectors are generally compatible with air, water, coolant, and light fuels. PP variants offer broader chemical compatibility. They are not recommended for strong solvents, concentrated acids, or high-temperature steam without first confirming material compatibility.
