Radium Engineering 12AN Female Fitting To Air Filter | Universal (20-0485)

The end of every vent line should breathe through a filter, not an open hose.

The Radium Engineering 12AN Female Fitting to Air Filter terminates high-flow vent lines correctly: the 12AN female end threads onto the vent line's male flare, and the integrated air filter breathes both directions, letting air escape during fills and filtered air return as fuel is consumed, without dirt riding in.

What You'll Feel

• The vent circuit finished with filtered breathing instead of an open line
• Dirt kept out of the fuel cell through every inhale
• Full 12AN flow preserved for quick-fill exhale rates

Features

• Air filter with 12AN female connection
• Two-way breathing: exhale during fills, filtered inhale during consumption
• Matches Radium's high-flow 12AN quick-fill vent architecture

The Details

Vent lines terminate somewhere, and that somewhere determines what the tank inhales for years: an open hose end drinks dust, spray, and debris straight toward the fuel, while the filter termination breathes clean. The 12AN sizing pairs with Radium's quick-fill DSV and 3/4" vent hose, keeping the whole circuit's flow capacity intact through the filter. Mount the filter at the vent run's high point per Radium's routing rules, protected from direct spray, and service it on inspection. Sold individually.
