Radium Engineering Vacuum Port Adaptors - Universal
Radium Engineering vacuum port adaptors screw into the 10-32 threaded vacuum/boost reference port on Radium components – including the MPR, DMR, FST-R, FPD-R, FPD-XR and FPR-D regulators and dampers and applicable Radium fuel hangers – and convert it to the reference line of your choice. Options cover a 3AN flare hose, a 5mm barb for rubber hose (the adaptor supplied as standard with Radium FPRs and FPDs) and a 1/4" push-to-connect for hard plastic tubing.
Choose your fitting from the dropdown – each option lists both connection types.
Note: These adaptors are designed for Radium products with a 10-32 vacuum port; confirm your component's port thread before ordering. Read the supplied instructions before removing the factory-installed barbed nipple. The push-to-connect version requires 1/4" OD hard plastic tubing (sold separately). Installation by a professional is recommended.
