Description
Radium 12AN ORB 5-Bolt SAE Adapter (20-0439)
The Radium Engineering 12AN ORB 5-Bolt SAE Adapter allows a Radium Engineering DSV (Dump can Shutoff Valve) to be used on older generation FCST (Fuel Cell Surge Tank) units that feature 8AN ORB vent threads (20-014X-XX series). This adapter bridges the thread size difference, enabling DSV compatibility on legacy tanks without replacing the entire unit.
Important Note: A fuel level sender cannot be used in conjunction with this adapter when installed.
Compatible Applications
- Radium FCST units with 8AN ORB vent threads — 20-014X-XX series
