Radium 1/8" NPT Male to 3/16" Barb 90 Degree (4.8mm)

Radium 1/8" NPT Male to 3/16" Barb 90 Degree (4.8mm)

This precision-machined 90° adapter fitting converts a 1/8" NPT male port to a 3/16" (4.8mm) hose barb connection. Ideal for routing vacuum, fuel, or fluid lines in tight spaces where a straight fitting would not clear surrounding components.

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.

Suits: Universal — any application with a 1/8" NPT male port requiring a 3/16" (4.8mm) hose barb connection
