Silicone rubber hoses perform extremely well under severe temperature and environmental extremes. Standard and custom silicone hoses have a useful life that is far superior to typical organic rubber materials and EPDM. Another reason to use silicone hose is that it is economical compared to bent metal tubes. Last, certainly not least, the trend towards more stringent emission requirements result in greater heat generation. Silicone is up to the challenge and increasingly the favored choice of design engineers.

High Temperature Resistance
Silicone hoses consistently outperform organic (black rubber or EPDM) hoses to high temperatures of 350° and 500°F when reinforced with aramid or Nomex™ fabric. Even under extreme conditions the silicone hose will retain excellent tensile strength, elongation, and tear & abrasion resistance.

Low Temperature Flexibility
Silicone hose can maintain dynamic flexibility to temperatures as low as -65°F.

Compression Set Resistance
Silicone hose is superior to other elastomers in resistance to compression set or deformation, particularly at high and low temperatures. This is particularly important when a silicone rubber part is used in a bellows application where the component is placed under pressure or is flexed often where there is movement between components.

Weather & Ozone Resistance
Silicone hose substantially resists the deteriorating effects of sunlight, ozone, rain water, and atmospheric gases, that cause weathering. Even in a very dry environment combined with harsh sunlight our silicone hose will perform well.

Water Resistance
Silicone rubber is noted for its water resistance. It has an extremely low degree of water absorption and its mechanical properties show minimal change, even after long periods of immersion.

Chemical Resistance
Silicone hose has excellent resistance to many common chemicals, fluids and oils. Examples of some chemicals that silicone rubber is resistant to are;

• Citric Acid • Heavy Water • Sodium Hydroxide
• Vegetable Oil • Potassium Chloride • 3 mole Methanol
• Natural Gas • Vegetable Oil • Ethylene Glycol (anti-freeze)
• Cold Oxygen • Water Zinc Salts • Water Solution Detergent
