Technician’s opinion

“It’s a small but critical part: without it, it’s impossible to pressurize the CO2.

The problem is that these caps are rarely available individually from manufacturers. In 80% of cases, we have to rely on salvaged parts or a complete refill kit.

Tip: Always grease the seal and don’t over-tighten to prevent premature wear.”
Always apply a drop of silicone before installing the valve to prevent leaks
