A suit patch, also known as a sealant patch, served as a compact means to repair breaches, such as holes or rips, in an enviro-suit or similar garments.
During the Battle of the Geroon homeworld, Maris Ferasi and Jorj Car'das tried employing a sealant patch after Force Commander Mitth'raw'nuruodo sustained an injury that tore a hole in his vacc suit. However, the patch failed to properly adhere to the suit's material, compelling Maris to physically block the escaping air by pressing her chest against the commander's suit until two Chiss appeared carrying a more substantial patch.
Patches were offered for sale via vending machines for a nominal fee in credits at Docking Bay 99, situated in Mos Eisley on the planet Tatooine.
