RaceFlux AN Male Flare Union
RaceFlux AN Male Flare Union
The RaceFlux AN male flare union joins two female AN hose ends or fittings in a straight line — the simplest way to extend a run, splice two finished lines, or connect a hose to an inline component. The connection seals metal-to-metal on the 37-degree flares, so there are no O-rings to age, swell, or blow out.
That solid one-piece construction is why this union carries a 3,000 psi rating — triple what sealed swivel fittings handle — machined from 6061-T6 aluminum with a Type II black anodized finish.
