Seamlessly step down from a 9.5mm (3/8") line to an 8mm (5/16") line with this compact Duotight reducer. Suitable for use with EVABarrier beer and gas hosing — just push, click, and you're sealed. No clamps, no tools, no fuss.
The BLUE 9.5mm side accepts 9.5mm OD EVABarrier line, and the BLACK 8mm side accepts 8mm OD EVABarrier line — colour-coded collets make it impossible to mix up.

Generation 2 Duotight — What's New?
- Colour-coded collets — 6.35mm (1/4") = Green | 8mm (5/16") = Black | 9.5mm (3/8") = Blue
- Burst pressure over 300psi @ 25°C
- Polyketone (POK) body — upgraded from Acetal (like John Guest fittings) for higher chemical & UV resistance
- Excellent gas barrier properties with EPDM + Silicone dual O-ring seals
- Superior performance in cold temperatures
- Gauge depth indicators >| |< for easier, more accurate fitting
Why Double O-Rings?
The secret to duotight's superior sealing is the combination of two different O-ring materials working together:
- EPDM — high gas and chemical resistance, but can shrink slightly when chilled
- Silicone — highly chemical resistant and maintains its shape in sub-zero conditions
Together, they provide twice the sealing surface compared to single O-ring push-in fittings, significantly reducing the chance of leaks across a wide range of temperatures and applications. The double O-ring system also allows the hose to bend at a much tighter radius without causing leaks — a common issue with other fittings.
No clamps necessary. We recommend cutting your hosing straight (not on an angle) to ensure a complete seal. To remove the fitting, simply push in the collet and pull the hose out.
