Crosman Stainless Steel High Performance Valve body and Stainless Steel Screw.
Made so you can change the Co2 bottle seal easily by just unscrewing the front and replacing the Co2 seal.

You can add an extra seal when you order under the options tab.

The standard brass one has the seal held in place by rolling the front edge over and is not made as a servicable item, so is a throw away and you have to buy a new complete valve and valve body. This one you can change the seal as many times as needed. But they will last a long time.

The Valve body comes with the centre body seal and the Co2 Seal.

I have added the option to add our Stainless Steel Exhaust Valve that unscrews for easy replacement of the seal for only £19.50

I have now put the Exhaust Valve Spring on this site as an option.
