This 304 stainless steel swivel nut and stem set is the professional standard for connecting flexible 1/4" ID tubing to male flare (MFL) ports on keg couplers, gas regulators, and manifolds. The two-piece design allows the 1/4" FFL nut to rotate independently of the 1/4" hose barb, preventing hose kinking during installation and ensuring a high-torque, leak-proof seal. Constructed entirely from food-grade stainless steel, this set is impervious to the corrosive effects of CO2, nitrogen, and acidic beverages, offering a significant durability upgrade over standard brass fittings.
- Nut Size: 1/4" Female Flare (FFL) / 7/16" - 20 Thread
- Barb Size: 1/4" OD Hose Barb
- Material: 304 Grade Stainless Steel Nut and Stem
- Configuration: Two-piece Swivel Set (Independent Rotation)
- Application: Gas line connections, jumper lines, and keg coupler inlets
- Durability: 100% rust-proof and resistant to all brewery cleaning chemicals
- Compatibility: Designed for 3/16" or 1/4" ID vinyl and braided beverage tubing
Technician's Note: Flare-to-flare connections (FFL to MFL) are mechanical seals, but they always require a 1/4" nylon flare washer (gasket) to be truly gas-tight. Never over-tighten the swivel nut with a heavy wrench; hand-tightening followed by a quarter-turn with a faucet wrench is sufficient. For the barb side, we recommend a 10.5mm or 11.3mm Oetiker clamp. If you are using 3/16" ID "beer line," the 1/4" barb provides a very tight, high-security fit that is excellent for high-pressure carbonation setups.
