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.

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:

1. EPDM O-Ring: Provides exceptional chemical and gas resistance.

2. 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.
