Hose barb fitting to connect tube：Stainless steel hose barb fittings are designed to connect soft, flexible tubing in low-pressure applications. Will work well with rubber, vinyl, polyurethane or similar materials tubes.
Barbed Connection Style：The barb means the angled ridge or bump on the fitting, is sized for the inner diameter of the soft tubing.Barb grip onto tubing or hose, providing a secure hold.The soft tubing expands as it is pushed over the barbs. Then once past the barbs, the soft tubing relaxes and returns to its original diameter, gripping the barbs and forming a tight seal. When the tubing and stainless steel hose barbs are properly matched, they are extremely leak resistant.
