The 304 Stainless Steel One-Piece Swivel Nut and Stem is the professional’s choice for connecting 3/8" ID beverage or gas tubing to any standard 1/4" MFL (Male Flare) port. This integrated design combines the nut and the barbed stem into a single high-strength unit, eliminating the frustration of dropped tailpieces and ensuring a perfectly aligned connection every time. Whether you are hooking up a CO2 regulator, a secondary gas manifold, or a Cornelius keg coupler, this fitting provides a robust, leak-proof seal.

Constructed from 304-grade stainless steel, this fitting is engineered for longevity and food safety. Unlike chrome-plated brass, it will not pit, peel, or corrode when exposed to moisture or cleaning chemicals, ensuring that no metallic off-flavors ever enter your beer or soda lines. The 3/8" barb is precision-machined with sharp ridges to provide maximum grip on vinyl or braided tubing, making it the ideal upgrade for high-flow beverage systems where reliability is paramount.

Why Professionals Choose One-Piece Swivel Sets: Traditional two-piece sets (nut and separate tailpiece) are prone to leaking if the tailpiece isn't perfectly centered or if the internal nylon washer is missing. Our one-piece design provides a more stable foundation for the flared connection. While it features a metal-to-metal flare seat, we recommend using a 1/4" Nylon Flare Washer to ensure a 100% airtight seal against gas leaks, especially in high-vibration commercial environments.
