New Tuned for more volume and flow, Genuine Crosman Valve and Body unit for Crosman 2240 pistol and 2250 Ratcatcher and 2260 Rabbit stopper models.
They include the Exhaust Valve and return spring so are ready to be exchanged with the old one. 

These are new Valve bodies for the 2240 2250 2260 models, I have modified them to increase the volume and flow for more power.
These are the standard design with the brass rolled over to retain the seal.
