This is a single head valve seal for a nailer. This part is installed in the top of the cylinder and creates a seal for the head valve. If air is leaking from the top of the nail gun, it could be due to a damaged head valve seal. To access this part, you will need to remove the top cap. Gaskets such as this should only be used once for a secure seal, so if you have removed this part, it will need to be replaced.
