Radium 12AN Female Fitting to Air Filter

The Radium Engineering 12AN Female Fitting to Air Filter kit is designed for use with the Radium 20-0462 DSV (12AN ORB to 12AN Male Quick Fill) as a vented air filter for fuel cell applications. The kit includes an air filter and a 12AN female adapter fitting. A 12AN male vent fitting is required for installation (not included).

Note: Because the top of the fuel fill tube must not be higher than the location of this air filter, this kit is intended for use with direct fuel cell fill caps only — it is not suitable for remote filler applications.
