Duotight 8mm Flow Control Ball Lock Disconnect
Take full control of your pours with the duotight Flow Control Ball Lock Disconnect. Designed for 8 mm EVABarrier beer line, this compact FC disconnect lets you fine-tune flow resistance directly at the keg — no more relying on long lines or tiny IDs to balance your system.
Perfect for serving a wide range of beverage styles with different carbonation levels, this disconnect gives you fast, precise control over pour speed while reducing turbulence and foam.
Why This Flow Control Disconnect Is Better
- Flow control at the keg, not the tap — reduces turbulence & foaming
- Integrated duotight fitting — push your 8 mm line straight in; no clamps or extra fittings
- Use shorter lines — FC replaces the need for long or small-ID beer lines
- Super compact design — the smallest ball lock disconnect ever made; ideal for tight fridges
- Overmoulded poppet — safe to disconnect under pressure (up to 150 psi)
- Tool-free disassembly — easy to clean, even with hop debris
- Engineered POK body — ultra-strong, chemical-resistant, built for long life
- Stainless spring & bearings — durable, hygienic, brewery-grade

Flow Control vs Flow Control Tap
Typical flow-control taps restrict flow at the faucet, where head pressure is low — causing turbulence and foam.
Flow-control disconnects restrict flow before the beer line, keeping carbonation in solution for smoother, foam-free pours.
