Sealed Joints is a MOD in Metroid Prime: Federation Force. Only one copy of it can be equipped at a time. When used, it will increase the Mech's defensive capabilities and allow it to better resist the corrosive effects of Talvania Gas, and damage dealt by Bion storms. This is similar to the resistance properties granted by Samus Aran's Suits. "Increase resistance against Talvania Gas and Bion storms by 50%."
