Description
Radium Replacement Stainless Steel FPR Fuel Pressure Regulator Orifice
Application: Radium MPR, DMR, FPR-D and RA-Series DFPR regulators; Radium hangers and surge tanks with integrated regulator
Part Type: Replacement stainless steel fuel pressure regulator orifice

The Radium 14-0772 is a stainless steel replacement orifice for many Radium Engineering products, including the MPR, DMR, FPR-D, FST-R and a number of Radium fuel pump hangers.
A smooth radius entry promotes more laminar flow. This single stainless steel orifice replaces all of the earlier aluminium versions, suits both older regulators and RA-Series regulators, and is fitted as standard to every RA-Series regulator with the tool-free adjustment knob.
Key Features

Important Notes
- Use a medium-strength wicking thread locker, such as green Loctite, when installing to keep the orifice in place under harsh vibration
