Type TVU003 Fitting for UNF Connection

Brand: Burkert Fluid Control Systems

In medical, biological and chemical laboratory and analysis technology, UNF threads in combination with fittings are typically used to connect hoses (PTFE, ...) and pipes/capillaries (VA, PEEK, ...).

Bürkert valves of types 0117, 0127, 6123, 6124, 6603, 6604, 6605 and 6606 are available with a UNF-1/4-28 thread. Fittings for UNF connections consist of a basic screw joint and a clamping sleeve.

The connections can be assembled very easily and quickly. They are cavity-free and prevent the medium from swirling when it is transferred from the valve to the hose.

Assembly instructions: Tighten basic screw joint hand-tight only, never squeeze it. The clamping sleeve and the hose form a reliable seal without the use of other materials.
