Flareless Bite Type Fittings as per DIN 2353 , Hydraulic Tube Fittings

Flareless Tube Fittings consist of three main components: a body, a one-piece ferrule, and a nut. They are available in Carbon Steel, Brass, and Stainless Steel to suit a wide range of industrial requirements. With numerous configurations and sizes, these fittings are designed to meet the needs of almost any hydraulic or instrumentation application.

During assembly, the ferrule “bites” into the outer surface of the tube with sufficient strength to hold the tube securely against pressure while creating a tight seal, without causing significant distortion to the inner tube diameter. Hydraulic fittings feature a visible bite, allowing installers to visually inspect the bite quality, thereby minimizing the risk of improper assembly and reducing potential service issues.

Flareless Tube Fittings are particularly suitable for tube wall thicknesses ranging from medium to extra heavy. Proper bottoming of the tube inside the fitting is essential to ensure correct bite and secure make-up. When assembled correctly, bite-type fittings provide reliable, leak-free performance without the need for special installation tools, making them efficient and easy to use in high-pressure systems.
