Barb Fittings
Barb fittings can be used to secure either soft plastic tubing or reinforced hose material. It is recommended to use Koolance spring clamps with plastic tubing, and ear clamps for either tubing or reinforced hose. (Koolance barb fittings include spring clamps.)

ID: 06mm (1/4in)
Barb fittings can be used with flexible tubing or reinforced hose. Includes straight and elbow (90 degree angled) versions in black and nickel plating. 6mm (1/4in) fittings are an effective choice for low clearance applications like rack mounted and blade servers.
ID: 10mm (3/8in)
Barb fittings for use with flexible tubing or reinforced hose. Includes straight and elbow (90 degree angled) versions in black and nickel plating. 10mm (3/8in) fittings are a great balance, typically providing the same thermal performance as 13mm (1/2in) tubing, but are easier to incorporate.
ID: 13mm (1/2in)
Barb fittings for use with flexible tubing or reinforced hose. Includes straight and elbow (90 degree angled) versions in black and nickel plating. 13mm (1/2in) loops can provide a high flow rate with less restriction.
ID: 19mm (3/4in)
Barb fittings for flexible tubing or reinforced hose. Includes straight and elbow (90 degree angled) versions in black and nickel plating. 19mm (3/4in) loops are used in industrial systems with very high flow rates.
