FEATURES

• Use where a reduction in tubing diameter is needed
• Use to reduce tubing flow

The 1.6 / 3.2 mm tube reduction fitting is ideal for reducing the diameter of the tubing, e.g., in a resting chamber setup. If the pump flow of water is too fast, you can introduce a reduction fitting along with tubing with smaller inner diameter (ID) to reduce the overall flow.
