Laboratory screw joint as connection between fitting and tubing/tube

Example 1:

If you want to connect three tubes/ tubings with O.D. 6 mm
you will need:

A 1 piece of GL tube fitting T GL 14 – Cat. No. D 540-14
B 3 pieces of HT laboratory screw joints GL 14 for tubing O.D. 6 mm,
Cat. No. D 628-74

Example 2:

If you want to connect tubing with different O.D. (2 mm and 6 mm) in an angle of 90°, you will need:

A 1 piece of GL tube fitting elbow GL 14 – Cat. No. D 539-14
B 1 piece of HT laboratory screw joints GL 14 for tubing O.D. 6 mm,
Cat. No. D 628-74
C 1 piece of HT laboratory screw joints GL 14 for tubing O.D. 2 mm,
Cat. No. D 628-34
