ITEM DESCRIPTION: 10pc Copper "D" style Exhaust Gasket, measures 30x23x4.5mm used on GY6 50 125 & 150cc engines found on various Scooters, ATVs, Sand  Dune Buggies, Trikes, etc...
 
NOTE: The cross-section of this gasket is the shape of a D.. (it's flat on one side and rounded on the other). The rounded side faces out to allow crushing and a better seal.
