Powerkit.68 V2 for Umarex HDB68 / TB68 (7.5J Version) – Export Valve | V2A Stainless Steel | 50+ Joules

Push your Umarex HDB68 or TB68 to the absolute limit with the all-new Powerkit.68 V2 – a performance upgrade engineered for maximum output. This kit is designed specifically for the 7.5J version, but also works with the 16J and 40J variants.

The CNC-machined V2A stainless steel valve pin features a shortened thread (3 mm less) for deeper insertion and optimal gas flow. The result? A power boost of well over 50 joules, depending on your setup and CO₂ temperature. No irreversible modifications needed – and the tuning remains completely invisible, inside and out.

✔️ Designed for Umarex HDB68 / TB68 – 7.5J version
✔️ Also compatible with 16J & 40J – no insert needed, just the pin
✔️ Shortened thread for max penetration and output
✔️ Hexagonal bore (2.5 mm) – better CO₂ expansion
✔️ Over 50+ joules possible (temperature-dependent)
✔️ Ultra-smooth finish – protects O-rings and internals
✔️ Completely reversible – no visible changes
✔️ Not an original Umarex part – engineered by Z-RAM

💡 Tip: For best performance, store your CO₂ cartridges at room temperature.
