Radium 12AN Female Fitting to Air Filter – Breather Adapter

The Radium 20-0485 adapter assembly provides a filtered vent solution for fuel cells using a 12AN male fitting. Commonly used with Radium's DSV (Dual Stage Vent) or 12AN ORB to 12AN male fittings, this adapter includes a compact air filter and 12AN female fitting. Designed for use in direct-mount fuel cell configurations, it ensures safe pressure equalisation while filtering airborne contaminants.
