duotight - 6.35mm (1/4'') x Ball Lock Disconnect (Black + Yellow Liquid)

The integrated duotight design means you can connect your liquid line directly into the disconnect, easily and reliably - no need for additional fittings or clamps. It is a robust and super compact design that is incredibly easy to assemble and disassemble, making cleaning and sanitising an absolute breeze!

Made from highly chemical-resistant materials with stainless springs and ball bearings - no cheap ABS plastics here - this fitting is extremely resistant to commonly used chemicals such as phosphoric-based sanitisers and caustics.

The incredibly small form factor allows for easy stacking of kegs. The new cap design ensures a pressure seal with just hand tightening, and it can be completely taken apart for cleaning with no tools required - no need to ever have blocked poppets again when it is this easy to disassemble and clean.

The robust and compact design makes this the best value and the best-designed homebrew quick disconnect ever manufactured.

Colour-coded for your convenience in Yellow and Black to indicate it’s your liquid line.

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

• Color-Coded Collets: Green denotes 6.35mm (1/4").
• 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.
