Crosman Discovery and King Ratcatcher Modified H Power Exhaust Valve, with reduced high flow stem.

The standard exhaust valve does not dismantle so you cannot change the seal. Ours is modified so you can unscrew the stem from the head for seal replacement. Replace seal with smooth side out.


Always check the power to make sure the gun does not exceed your limit, after changing any parts.

This is not suitable for the standard Ratcatcher or Rabbit Stopper as it does not have the piercer point, to pierce the 12gm bottle.Saves you money in the long run as you do not have to keep buying a new valve when it starts to leak.
