New Tuned for more volume and flow, Crosman Co2 Valve unit complete giving a higher Output for Crosman 2240/2250/2260 (but not for king Rat or HPA), Latest Genuine unit with Stainless steel retaining screw.
Whole new latest with screw as the new ones have a different screw AND ARE NOT INTERCHANGEABLE, so I supply mine with the new screw so you can easily change them over.
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 Valve and body seals are rolled over to retain the seal.

I do a new seal set for all the Crosman 2240 Pistols, 2250 Ratcatchers and 2260 Rabbit Stoppers.

Although the seals are not meant to be changed but you can change them. Watch the Video on how to change the seals on my Youtube channel.  Under TR Robb Airgun Specialist.
Check power after fitting.
