Sealing gasket for co2 valve all im and jm models.

The 'DANiNJECT* sealing gasket is one of the most important service parts.

You should always have an extra sealing gasket in your DANiNJECT equipment box ready to replace.

For the IM model it is used if you used an ADAPT16 adaptor for 12 and 16gram CO2 cartridges.
