How to make your order
A screw joint always consists of two elements
1. Fitting (straight, elbow, T-shape or a GL thread of a glass device)
2. Laboratory screw joint as connection between fitting and tubing/tube
Example 1
A screw joint always consists of two elements:
A 1 piece of GL tube Fitting T GL 14
B 3 pieces of Laboratory Screw Joints HT GL 14 for tubing O.D. 6 mm
Example 2
If you want to connect tubing with different O.D. (2 mm and 6 mm= if an angle of 90°, you will need:
A 1 piece of GL Tube Fitting Elbow GL 14
B 1 piece of Laboratory Screw Joints HT GL 14 for tubing O.D. 6 mm
C 1 piece of Laboratory Screw Joints HT GL 14 for tubing O.D. 2 mm
