Raw Material

Our standard silicone hoses are engineered to meet a wide range of industrial and automotive requirements. Manufactured using premium VMQ (Vinyl Methyl Quality) silicone compounds and reinforced with high-tensile polyester fabric, they deliver reliable performance in both coolant (water-glycol) and air transfer systems.

These hoses are designed to operate in extreme temperature conditions, withstanding continuous exposure from -60°C to +180°C, making them ideal for applications where thermal stability, flexibility, and durability are essential.

Technical Specification

  • Base: VMQ (Vinyl Methyl Quality)
  • Reinforcement: High-tensile polyester fabrics
  • Color Options: Standard blue, red, black (custom colors available)
  • Operating Temperature: -60°C up to +180°C (standard) – under demand we can offer Aramid Fabrics construction These hoses are engineered to operate in extreme temperature conditions, withstanding continuous exposure from -60°C up to +240°C.
  • Wall Thickness: Typically 4–5 mm (customizable)
  • Pressure Rating: Up to 6 bar (depending on diameter and wall thickness)
  • Vacuum Resistance: Up to -0.9 bar
  • FVMQ (Fluorosilicone): High temperature resistance and oils and chemicals resistance
  • FKM (e.g. Viton®): High temperature resistance and oils and chemicals resistance
  • Aramid Fiber (e.g. Kevlar®): Up to 240°C
  • Fiberglass: Up to 250°C (peks to 280°C)


In addition to our standard range, we offer customized silicone hose solutions tailored to specific requirements whether in terms of geometry, material formulation, or reinforcement layers to meet the most demanding technical specifications
