Description
Radium AN Male to NPT Male Fittings
These precision-machined adapter fittings convert AN male flare connections to NPT (National Pipe Thread) male ports. NPT fittings seal via the intentional interference created by tapered threads meshing together — always use a small amount of PTFE paste or tape on NPT threads, tighten to finger tight, then add a further 1.5 to 3 turns until secure.
Available in 4 configurations across 6AN and 8AN sizes with 1/4" and 3/8" NPT, in straight and 90° options.
Suits: Universal — fuel systems, oil systems, and all NPT-ported components
