Green CO2 bulb seal for the following most Gletcher air pistols

This is the seal against which the CO2 capsule fits and the most common to be replaced.
Generally needs to be replaced if a CO2 capsule has been left in the airgun for a long time, which causes leaks when the CO2 is replaced.

Please check yours has the green seal before ordering.
