Plastic Barbed Hose Connectors — Reliable Joins for Air, Water & Fluid Lines
Dealing with split tubing, leaky joints, or mismatched hose sizes mid-project? Whether you're a DIYer routing irrigation lines, a hobbyist building pneumatic rigs, or a technician repairing fluid systems, finding the right plastic barbed hose connector in the exact size you need shouldn't slow you down. These fittings are stocked in an extensive range so you can grab exactly what your system calls for.
Each pack contains 5 pieces of the same connector type and size. Available connector styles include T-Piece, T-Piece Reducing, Elbow, Elbow Reducing, and Straight — with sizes ranging from 1.6mm (≈1/16") up to 32mm (≈1-1/4"). Reducing variants allow you to join two different-diameter tubes in a single fitting. The plastic construction keeps fittings lightweight and corrosion-resistant for both air and water service.
Typical use cases include garden drip irrigation and soaker hose repairs, aquarium and hydroponics tubing connections, pneumatic airline routing in workshops, and automotive coolant or vacuum line splicing. The wide size range makes these plastic barbed fittings a go-to for anyone managing multi-diameter tubing systems.
🔗
Compatibility Note: Select the barb size that matches your tubing's inner diameter (ID). PE-labeled variants are sized for polyethylene tubing. Reducing variants connect two different tube sizes — check the size label (e.g., "8mm – 10mm") before ordering.
✅ Key Features of These Plastic Barbed Hose Connectors
-
📐Wide Size Range — Available from 1.6mm (≈1/16") to 32mm (≈1-1/4"), covering the most common tubing IDs used in irrigation, pneumatics, and fluid transfer systems.
-
🔀Four Connector Styles — Choose from Straight, Elbow (90°), T-Piece, and Reducing variants to handle inline joins, direction changes, branch splits, and diameter transitions in a single product line.
-
💧Air & Water Rated — Designed for low-to-medium pressure air lines and water tubing, making these barbed fittings suitable for garden irrigation, aquarium plumbing, and workshop pneumatic lines.
-
🛡️Corrosion-Resistant Plastic Body — The engineering-grade plastic construction resists rust and chemical corrosion, extending service life in damp or wet environments compared to metal alternatives.
-
📦5-Pack Quantity — Each order ships as a 5-piece pack of identical connectors, giving you spares for repairs, replacements, or multi-point installations without over-ordering.
-
⚙️Tool-Free Push-On Installation — The barbed design grips tubing securely on insertion without tools or adhesives. For higher-pressure runs, a standard hose clamp can be added for extra retention.

Size Tip: If your tubing is labeled in inches, use these approximate conversions: 1/8" ≈ 3.2mm, 3/16" ≈ 4.8mm, 1/4" ≈ 6.4mm, 5/16" ≈ 7.9mm, 3/8" ≈ 9.5mm, 1/2" ≈ 12.7mm, 5/8" ≈ 15.8mm, 3/4" ≈ 19mm, 1" ≈ 25mm.
❓ Frequently Asked Questions
How do I choose the right barbed connector size?
Match the barb size to your tubing's inner diameter (ID). For example, a 6mm barb fits tubing with a 6mm ID. If you're working in inches, 1/4" tubing is approximately 6.4mm, and 3/8" is approximately 9.5mm. When in doubt, measure your tubing ID with calipers before ordering.
What materials are these barbed fittings made from?
These connectors are generally made from engineering-grade plastic (typically nylon or polypropylene). They are lightweight, corrosion-resistant, and suitable for low-to-medium pressure air and water applications.
What is the maximum pressure these fittings can handle?
Plastic barbed fittings typically handle pressures up to 60–100 PSI depending on tubing size and wall thickness. For higher-pressure applications, we recommend confirming with your system specs or contacting us to confirm the rating for your specific size.
Can these be used outdoors or in wet environments?
Yes. The plastic construction is generally resistant to moisture and mild corrosion. However, prolonged UV exposure may degrade some plastics over time. For outdoor use, consider protecting fittings from direct sunlight or contact us to confirm material suitability for your environment.
Are these fittings compatible with PE (polyethylene) tubing?
Yes. Several size variants are specifically labeled for PE tubing (e.g., 4mm PE, 6mm PE, 8mm PE). PE tubing typically has a slightly different wall thickness, so selecting the correct PE-designated variant ensures a secure barbed fit without over-stretching the tubing.
What is the difference between Type A and Type B straight connectors?
Type A and Type B variants for the same nominal size generally differ in barb profile or body length to accommodate different tubing wall thicknesses or hose clamp styles. Check the size label carefully and contact us if you need clarification on which type fits your specific tubing brand or application.
Do I need hose clamps with these barbed fittings?
For low-pressure applications, barbed fittings typically hold securely without clamps when the tubing ID closely matches the barb OD. For higher-pressure or vibration-prone systems, using hose clamps is generally recommended for a leak-free, long-term connection.
