VERNATUBE™ is a resin-impregnated glass filament wound tubing wound exclusively with a fire retardant resin formulated for high temperature applications. Centek uses the fire retardant VERNATUBE™ to fabricate many of the basic components used to manufacture our wet marine exhaust systems. VERNATUBE™ exceeds values for the class of materials designated as “self-extinguishing” per ASTM –D-635, UL94V-O, and the US Navy/USCG MIL-R-21607 and MIL-R-7575. The smooth, resin-rich I.D. assures minimal restriction to exhaust gases and cooling water flowing through the tubing. Precise control of the outside diameter ensures ease of connecting mating ports with marine exhaust hose.
