Duotight 8mm (5/16) x Ball Lock Disconnect - (Grey + Red Gas)

Push-fit ball-lock gas disconnect — 8 mm (5/16") CO₂ line straight in, no clamps.

The duotight ball-lock disconnect swaps the usual barb-and-clamp for an integrated push-in fitting: push your 8 mm EVABarrier gas line in and it locks. Compact, chemical-resistant and fully hand-serviceable — ideal for tight kegerators or stacking kegs. This is the gas (CO₂-in) version for larger 8 mm line.

Key points

• Integrated 8 mm (5/16") duotight push-in — connect EVABarrier gas line directly; no threaded adapters.
• Overmoulded poppet — couples and disconnects up to 150 psi without o-ring blow-outs.
• Ultra-compact body — maximises space and lets you stack ball-lock kegs while connected.
• Tool-less strip-down — hand-loosen the cap to clean; no screwdriver.
• Chemical-resistant — handles phosphoric, caustic and peroxide cleaners.

Specifications

Use & care: Cut the tube square, push it fully home, then tug to confirm it's locked. To release, press the collar and pull the tube out. Hand-tighten only — no tools. Strip by hand to clean, then rinse and dry before reassembly.
