Award-Winning HTA Gaskets Solve a High-Temp Challenge
There might have been a day when exhaust gaskets were considered “low tech.” Thanks to rapidly rising exhaust gas temperatures and strict new emissions requirements, completing a quality exhaust sealing repair now calls for the very latest gasket materials and designs.
But don’t worry – Federal-Mogul’s Payen® and Goetze® brands have solved this challenge with their award-winning HTA™ (High Temperature Alloy) exhaust gasket technology. Already in use by engine and vehicle OEMs, HTA gaskets offer high-temperature micro-sealing and reduced friction for each joint in an exhaust system as well as EGR manifold applications.
Winner of the prestigious Automotive News PACE™ Award for product innovation, HTA gaskets combine application-specific high-temperature alloys with an advanced high-temperature coating to provide reliable performance in operating temperatures up to 1000 °C. Conventional single or multi-layer stainless-steel gaskets may start to lose tensile strength and sealing effectiveness at temperatures above 450 °C, while other common replacement gasket materials and coatings – including graphite, mica and molybdenum disulphide – degrade at 600 °C and above.
“EGR technology and increased exhaust gas temperatures have dramatically impacted the sealing category, but the Payen and Goetze brands are already positioned to address this need,” said Alexis Goslin, Federal-Mogul product manager, sealing, Europe, Middle East and Africa. “Using a conventional exhaust gasket on a late-model turbocharged diesel engine, as just one example, could lead to an expensive comeback.”
Turbocharged diesel and gasoline engines produce significantly higher exhaust gas temperatures than conventional engines. In addition, the ability to provide leak-free micro-sealing throughout an exhaust system is particularly important with today’s emissions-compliant engines. Even minor leaks in any exhaust joint can undermine the performance of the engine and emissions control system. Using conventional replacement gaskets on a high-temperature application can lead to thermal fatigue, oxidation, creep relaxation, galling, and other damage to the gasket material, ultimately causing unwanted leaks.
“HTA technology is another example of the importance of relying on an aftermarket supplier that is also a globally recognized innovator at the OE level,” Goslin said.
