LOC-LINE (1/4") 41412 SAE Flare Nut Adaptor (3/8")

The Loc-Line 41412 is a ready pack solution (4 adapters) for converting existing 3/8″ SAE flare copper connections into the 1/4″ flexible Loc-Line system. Built from durable, non-conductive acetal, it withstands coolant, oils, and moderate pressure while providing easy modularity for machining, CNC, or air delivery setups.
