Let’s discuss the quality and design of Cometic Gasket’s line of V-Twin gaskets, which are made to perform better than most stock and aftermarket offerings.
Cometic makes gaskets for a ton of Harley-Davidson applications. The company also uses reinforced gasket material compounds like armor-clad, graphite, and galvanized steel. All of which are also constructed for sealing irregular surfaces, like, say those in an engine.
They designed their Armor Ply as a high-performance metal reinforced gasket material for sealing irregular surface flanges in high heat applications. It features a steel layer on one side with a graphite layer on the other and a fiber layer between.
The Armor Clad version differs from the Armor Ply a bit. It features a steel layer on one side with a graphite layer on the other and a fiber layer between. Like the Armor Ply, it’s also made for irregular surfaces and high heat. Cometic recommends it for exhausts and turbo flanges.
The HTS Fiber gaskets feature a graphite/fiber blend. It’s mechanically bonded to a perforated stainless steel core. The facing material features 75% graphite with Kevlar fiber reinforcements for strength and durability. Unlike the armored versions above which top out at 1200F, HTS Fiber runs to a short duration max temp of 1400F. Cometic advises using HTS Fiber for intakes, exhausts, and turbochargers.
Cometic Gaskets CFM-20 packs a tanged and galvanized steel core. The asbestos-free soft material compound contains aramid fibers, inorganic fillers, and high-grade binder elastomers. All applied to both sides of the core. Find your Harley gasket on the company website.
