About Silicone Hose |
| .................................................................................................................. |
| |
Silicone Hose construction is with smooth wipe down finish. Temperature range of this hoses is -50°C to 300°C. The working pressure is 0.3~0.9Mpa, the burst strength is 1.9Mpa. Thickness range: 2mm to 7mm with 1 to 5/6 mesh Polyester or Aramid & Glass fabric layers to enable high temperature and pressure than original rubber hose do. It is excellent resistance to UV, water, ozone and oxygen.

| Our Hose meet or exceed the classification of |
• SAE J20 R1 CLASS A
• SAE J20 R2 CLASS A
• SAE J20 R3
• SAE J20 R4 CLASS A |
