Pressure hoses

Silicone pressure hose – Reinforced with stainless steel wire

For demanding pressure applications: The reinforced silicone pressure hoses in the SDU series from BIW combine the elasticity of high-quality silicones with the stability of an internal stainless steel wire. Resistant to high temperatures, chemicals, UV radiation and pressure loads – ideal for professional use in industry, food technology or laboratory environments.

Product description

The silicone pressure hoses in the SDU series have been specially developed for applications where high pressure loads as well as chemical and thermal resistance are required. By inserting a stainless steel wire (material 1.4301), the silicone hose is stabilised while remaining flexible and elastic.

The transparent basic bodies are made of high-quality, chlorine-free silicone and fulfil the highest hygiene standards – suitable for contact with food or pharmaceutical media. The pressure hose is suitable for laboratory and process technology, mechanical engineering, medical technology and more.
