This Straightline Performance nitrous oxide bottle valve is a low-profile, non-siphon valve designed for 2.5 lb bottles and setups where the bottle is mounted upside down. Its compact body fits into tight spaces, while the side-mounted knob lets you control flow easily even in cramped installations.

Built for high-performance nitrous delivery, the valve provides optimized flow and a secure, reliable seal on 3/4-inch bottle necks. It is a direct-fit replacement for custom and race builds that need precise control without extra bulk.
