Description
A replacement air chamber and valve chamber assembly for the Umarex T4E HDB 68 and TB 68 .68 calibre markers. It is intended for owners who need to repair or service the internal gas system of their marker.
- Spare part for the Umarex T4E HDB 68 and TB 68
- Air chamber and valve chamber supplied as one assembly
- Lets you replace worn or damaged internals rather than the whole marker
The HDB 68 runs on 12g CO2 capsules, so always remove the capsule and make sure the marker is fully de-gassed before opening it up. If you are not confident working on gas internals, have the part fitted by an experienced technician.
