The Snow Performance inline check valve adapts -6AN fittings to an M12x1.5 connection while preventing reverse flow in the fuel line. Compact and purpose-built, it lets you add a check valve where an -6AN to M12x1.5 transition is needed without modifying existing plumbing. Use it to maintain one-way flow in fuel or fluid circuits that require that specific adapter interface.
