Note on Fitment: We used two different seal styles on the Pusher 3” HD Hot Side Charge Tube for 6.7L Powerstrokes.

Pre-Sept 2021 kits shipped with a standard O-Ring

Post Sept 2021+ kits ship with our improved X-Ring seal (better crush conformity and sealing under boost)

This part listing is for a replacement seal only - please verify which style you need before ordering. If you are unsure which seal your tube requires (or what year your kit shipped), call or email us with your order number / serial or a photo of your tube end and we’ll confirm the correct part.
