duotight – 9.5mm (3/8”) Female x FFL Female Thread (to fit MFL Disconnects)
This straight MFL joiner is suitable for our EVABarrier Beer & Gas hosing in 6mm ID x 9.5mm OD line or most lines with 9.5mm outer diameter to MFL Ball lock disconnects or any MFL type connection.
The FFL x 9.5mm duotight is suited to those who prefer to have their gas line a different thickness so that it can be easily identified in a tangled like situation inside a fridge/keezer/kegerator.
Applications & Compatibility
- MFL Disconnects: Screw directly onto Grey (Gas) or Black (Liquid) MFL Ball Lock or Pin Lock disconnects.
- Regulators: Fits MK4 Regulators and other homebrew CO2 regulators with MFL outputs.
- Threaded Fittings: Compatible with any 1/4" MFL male thread.
9.5mm Tubing Compatibility
This 8mm duotight fitting is optimised for use with EVABarrier Dual Barrier Line. It is compatible with:
- KL06248: EVABarrier 6.3mm ID x 9.5mm OD x 12m Roll - Double Wall EVA
- KL42772: Black Lightshield EVABarrier 6.3mm ID x 9.5mm OD x 12m Roll - Double Wall EVA
The duotight Generation 2 Difference
Why settle for standard push-in fittings? duotight Generation 2 represents a massive leap in engineering over traditional acetal fittings.
Dual-Material Double O-Ring Design
The secret to our superior seal is a two-stage system using two different high-quality materials:
-
EPDM O-Ring: Provides exceptional chemical and gas resistance.
-
Silicone O-Ring: Maintains its shape and elasticity in sub-zero temperatures.
High-Performance Materials (POK)
Instead of standard Acetal, Generation 2 fittings are made from Polyketone (POK).
- Higher Chemical Resistance: Withstands harsh brewery cleaners.
- UV Protection: Won't become brittle over time.
- Extreme Durability: Rated for over 300psi @ 25°C.
User-Friendly Features
- Colour-Coded Collets: Blue denotes 9.5mm (3/8").
- Depth Indicators: Includes >| |< indicators so you know the hose is fully seated.
- No Clamps Necessary: Simply push to seal; push the collet to release.
We recommend using a Tube Cutter to ensure a perfectly straight, burr-free cut. An angled cut is the #1 cause of leaks in push-fit systems.
