COUPLING BARB

Our Barbed Couplings provide a quick, secure way to connect two sections of flexible tubing in pond, irrigation, fountain, or low-pressure plumbing systems. Designed with double barbed ends, these couplings ensure a tight fit and prevent leaks when used with hose clamps.

Available in both equal (straight) and reducing (step-down) configurations—from 3/8" to 1-1/2"—these durable plastic fittings are ideal for creating or repairing tubing runs without rigid PVC components. The ribbed design offers strong grip and easy installation for smooth, uninterrupted water flow.

Key Features:

• Barbed Coupling Design: Connects two tubes of the same or different sizes

• Strong, Ribbed Grip: Prevents slipping and improves seal with hose clamps

• Durable Construction: Made from high-impact plastic that resists UV and corrosion

• Available in Straight & Reducing Sizes: Including 3/8", 1/2", 3/4", 1-1/4", 1-1/2"

• Easy to Install: Just insert and clamp—no glue or threading required
