Nylon Flare Washer

The nylon flare washer is designed to fit within a ¼” MFL swivel-nut-and-barb assembly.  For example, the nylon flare washer is used to prevent leaks (either gas or liquid) when assembling a metal-to-metal connection between a ¼” MFL tail piece to a ¼” swivel nut or a CO2 regulator to a ¼” swivel nut.
