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; surround all bolt holes. Assemble parts immediately. Finger tighten bolts until material begins to squeeze out around flange. Allow to dry for one hour then retighten 1/4 to 1/2 turn.
