Application
Designed to replace hard-to-handle and easily
damaged capillary tubing giving a more predictable
pressure drop.
Agency Approvals
UL Recognized; File No: 2709
Features and Benefits
• Cost effective alternative to capillary tubes.
• One piece design.
• Versatility in length, end configuration, orifice size
and copper tube bend configuration.
• Easy to handle and install.

Flo-Rater Style FD20E
Application
Developed to solve space limitation
problems on Packaged Terminal
Heat Pumps and mini-split systems.
The FD20E utilizes two floating
orifices to replace two check valves
and two cap tubes along with up to
