Radium Engineering Universal 3AN Vacuum Port Adapter | Universal (14-0369)

Boost gauges and reference lines run 3AN; the manifold speaks NPT; one tiny adapter translates.

The Radium Engineering Universal 3AN Vacuum Port Adapter converts a 1/8" NPT port to a 3AN male flare, giving vacuum and boost reference lines a proper AN anchor at the manifold, regulator, or vacuum block. Machined anodized aluminum, sized for the small-bore signal lines that gauges, boost controllers, and vacuum-referenced regulators run.

What You'll Feel

• Reference lines connected with real AN hardware instead of pushed-on vinyl hose
• Signal integrity for boost controllers and vacuum-referenced regulators
• A leak-free tapered seal at the port with a serviceable flare above it

Features

• 1/8" NPT male to 3AN male vacuum port adapter
• Machined anodized aluminum construction
• For vacuum and boost reference lines: gauges, controllers, regulators

The Details

Small signal lines fail more often than big fuel lines, usually where soft hose meets a bare barb, and the fix is the same architecture the rest of the system uses: an NPT-sealed port adapter and a 3AN hose end that services like any other AN joint. The NPT end is tapered and thread-sealing, so apply PTFE thread sealant paste before installation, while the 3AN flare takes its hose end dry, hand tight plus 1/4 to 1/2 turn. Typical homes include intake manifold vacuum ports, Radium regulator gauge/reference ports, and vacuum distribution blocks. Sold individually.
