ULTIMATE Piston Head O-Rings - Pack of 5
- These are not typical piston head o-rings. They feature a grove on the inner edge of the o-ring which helps expand and create excellent compression when used in conjunction with a ported piston head.
- A pack of 5 quality O-rings for all AEG piston heads.
- Great for replacing worn, hardened or torn O-rings without having to replace the entire head.
- Suitable for every gearbox version.
