MEZ-ALUDEC AA3 - Ø 457

• Fully flexible and strong laminate hose
• Temperature range: -30 to +140°C
• Max. operating pressure: +2.500 Pa

MEZ-ALUDEC AA3 is a fully flexible and strong laminate hose for various applications. The hose consists of several layers of aluminium and polyester with a hidden wire spiral. ALUDEC AA3 can be easily mounted on round and oval connectors. The fire resistance of ALUDEC AA3 has been tested in several countries according to international standards. The fully flexible laminate hose is made of a specially developed "sandwich construction", which means that the different layers of polyester and aluminium completely overlap each other. This makes the construction particularly strong.
