A urea SCR system contributing to a better global environment
SUN-A Corporation applies the world's first independent sensor technology in its manufacturing
Kuriyama Group company SUN-A Corporation develops and manufactures heat-sensitive urea water identification sensors as one of its core products of urea SCR systems. With exhaust emission regulations becoming increasingly stringent worldwide, we provide urea SCR sensors, modules, tanks and other products that are suited to construction machinery, agricultural machinery and automobiles.


Highly Functional Products
We leverage our global supply chain and technology to solve your challenges.
We work with customers from the development stage to create various high-performance products.
Rubber hoses adaptable to various fluids and temperature ranges are proposed, including radiator coolant, diesel fuel, hydraulic fluids, and hot air compressed by turbochargers.
Anti-vibration rubber mounting reduces vibration transmitted from the engine to the operator and protects the engine from large external impacts.Our Rubber Mounting has been used in many cases on hydraulic excavators with particularly harsh operating conditions.
Bushing is inserted into the joints of booms, arms and buckets of construction machinery to enhance their sliding properties. Carbon steel, high strength brass and carbide, and PTFE composite materials provide bushings for a variety of applications.
NORMA Group products are comprised of high quality brands from around the world. Every sort of coupling component is available, from hose clamps to one-touch plastic connectors and metal fittings.
