Description
The Duotight 8mm x FFL Adapter provides a quick and reliable way to connect 8mm OD beer or gas line to MFL threaded keg disconnects. It is ideal when building or upgrading a kegging system.
The 8mm push-in connection accepts compatible tubing without a hose clamp. Meanwhile, the female flare thread screws directly onto compatible MFL threaded fittings. This makes it particularly useful with threaded ball lock and pin lock disconnects.

Duotight Generation 2
Duotight Generation 2 fittings use two O-rings made from different materials. First, the EPDM O-ring provides excellent chemical and gas resistance. Meanwhile, the silicone O-ring stays flexible at low temperatures.
Generation 2 fittings use Polyketone (POK) instead of standard acetal. As a result, POK provides excellent chemical resistance, UV resistance and durability for brewing and beverage dispensing systems.
Generation 2 Features
- Dual EPDM and silicone O-ring sealing system
- Durable Polyketone (POK) construction
- High chemical resistance
- UV resistant
- Rated to over 300 psi at 25°C
- Black collet identifies the 8mm (5/16″) connection size
- Tube depth indicators help show when you have fully inserted the line
- Push-in connection requires no hose clamp
For the best seal, first cut the tubing cleanly and square. Then push the tubing firmly into the fitting until it reaches the correct depth. To remove the tubing, press the collet in while pulling the line out.
