Career 707 seals.
Career 707 Set of main seals.
If you need any extra seals or valves other than those pictured then you can send it to me carefully wrapped so it does not get lost in the post, so I can Probably make a new one. There are a few variants of seals and valves in the 707. You may not need all the seals sent in the kit at I try to cover all variants.
Always check the power to make sure the gun does not exceed your limit, after changing any parts.
