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.
