Plastic Straight Barbed Hose Connector — Tubing Joiner for Air & Water Lines, 1.6mm–10mm

Match the connector size to your tubing's inner diameter (ID). For example, a 4mm connector (≈5/32") fits tubing with a 4mm ID. When in doubt, measure the inside of your tube with calipers. Sizes available range from 1.6mm (≈1/16") to 10mm (≈3/8"). If your tubing is labeled in inches, use the conversions listed in the specs table above.

Plastic barbed straight connectors are generally rated for low-to-medium pressure applications — typically up to 60–80 PSI depending on tubing material and temperature. For high-pressure systems, contact us to confirm suitability before ordering.

These connectors are made from plastic (typically nylon or polypropylene), which is generally resistant to moisture and mild corrosion. They are suitable for irrigation, aquarium, and outdoor water line use in most cases. Avoid prolonged direct UV exposure without a protective covering for best longevity.

These barbed connectors work with flexible tubing made from silicone, PVC, polyurethane, and similar soft materials. The barbed design grips the inner wall of the tube for a secure, leak-resistant connection. They are not designed for rigid pipe or hard plastic tubing.

Yes. These straight barbed joiner connectors are designed for use with both air and water lines, as well as other non-corrosive fluid applications such as aquarium tubing, drip irrigation systems, and pneumatic hobby setups.

In most cases, no. The barbed profile creates a friction-fit seal when tubing is pushed firmly onto the connector. For higher-pressure or vibration-prone applications, a small hose clamp is generally recommended for added security.

Both colors are functionally identical. Transparent connectors allow you to visually inspect flow inside the connector — useful for aquariums or fluid monitoring setups. White connectors blend in with white tubing or fixtures for a cleaner finished look.
