TRANSCRIPT
Premium Exhaust Clamping Technology across IndustriesNORMA Group has been the industry leader in the
design and manufacture of high quality exhaust
connections. Our Torca brand invented the reaction
block technology and thus set industry standards for
360° sealing performance.
NORMA’s wide-range of exhaust clamps are
designed, engineered and tested to meet stringent
OEM specifications and provide consistent sealing.
We specialize in delivering reliability and robust
performance even in extreme conditions.
