The Nitrous Express 6AN x 4AN x 4AN billet Pure‑Flo Y fitting provides a single-piece turbulence-reduced adaptor to split a 6AN feed into two 4AN outlets. Machined as a one-piece billet to avoid internal joints and flow-disrupting steps, it offers a smooth internal path for nitrous or fluid distribution. The red finish identifies NX's Pure‑Flo billet series.
