Cut nozzle to desired bead size gaskets are best formed using a 1/16" to 1/4" (2-6mm) bead.
Apply a continuous and even bead of silicone to one surface, surrounding all bolt holes. Remove excess with knife at once. Assemble parts immediately. Do not squeeze out silicone by over tightening bolts. Re-torque will not be necessary.
