MVK 19



Designed for long-term operation at temperatures up to 700°F (371°C), MVK-19 was developed to operate in severe environments.  MVK-19 components have been qualified in the hottest compressor stages of military and commercial jet engines for over 20 years. 

Reinforced with continuous fiber, MVK-19 components exhibit excellent thermal and mechanical stability under extreme conditions.  MVK-19 components are available exclusively from Maverick Molding Company.
