AF 404 flex

The asbestos-free fiber material 404 is an optimized sealing material for refrigeration technology and gas applications.

AF 404 is characterized by a particularly fine structure, which enables extremely low leakage. The high elasticity of the sealant ensures a reliable seal even under minimal surface pressure. The material properties also facilitate processing and allow for very thin web widths in complex seal geometries. AF 404 is ideally suited for use in gas systems, refrigeration circuits, and anywhere the highest demands are placed on gas tightness.
