Unique-Bargains 5pcs 3/8'' Barb Coupling Black 66x23mm

Tubing Coupling for Garden Irrigation

This pack contains five black plastic couplings designed to join two sections of tubing in garden irrigation systems. Each fitting accepts tube with an 8 mm inner diameter and 11 mm outer diameter on both ends. The barbed design creates a secure connection without requiring specialised tools or plumbing experience. They are a practical accessory for assembling or extending drip watering lines.

Barbed Connection and Material

Both ends feature a 3/8 inch barb profile that grips the tubing interior when pushed into place. The plastic construction keeps the assembly lightweight and resistant to corrosion in outdoor conditions. Installation is completed by hand, eliminating the need for clamps or adhesives in typical low-pressure setups. Normal use involves minimal friction loss across the joint.

66 mm Overall Length

The coupling measures 66 mm long and 23 mm in diameter, determining how much space it occupies between connected tubes. This fixed length suits standard irrigation layouts where components are spaced accordingly. Buyers needing a shorter or longer spacer between tube ends should consider a different fitting style. The five-piece quantity covers multiple connection points in a single purchase.
