Push-fit ball-lock liquid disconnect — 6.35 mm (1/4") line straight in, no clamps.
The duotight ball-lock disconnect swaps the usual barb-and-clamp for an integrated push-in fitting: push your 6.35 mm EVABarrier line in and it locks. Compact enough to stack kegs, fully hand-serviceable for cleaning, and built to disconnect safely under pressure. This is the liquid (beer-out) version.
Key points
- Integrated 6.35 mm (1/4") duotight push-in — connect EVABarrier line with no tools, clamps or adapters.
- Overmoulded poppet — couples and disconnects up to 150 psi without o-ring blow-outs.
- Ultra-compact body — fits tight keezers and lets you double-stack kegs.
- Tool-less strip-down — hand-loosen the cap to clean; no screwdriver.
- Chemical-resistant — handles phosphoric, caustic and peroxide cleaners.
