Silicone Hose Performance

Why use Silicone Hose?

Silicone rubber has historically been used in specialty applications in order to meet requirements other elastomers cannot.  Silicones have the largest application temperature span of all rubbers (-120 F to + 500 F).



Their chemical structure allows Silicones to be the most benign of all rubbers in medical applications, also having the longest shelf life.  For example, a coolant hose made with Silicone meeting SAE J20 is given a shelf life of 20 years, whereas those made with chloroprene rubber meeting SAE J20 are given a shelf life of 8 years.

Silicone hose has been a breakthrough in the automotive market, a perfect solution for radiator hoses and turbocharger hoses as well as oil pan and rocker cover gaskets.  Purosil silicone hoses are formulated to Mil specs, SAE specs and TMC specs. If you need to rely on the components of your engine, generator, turbo or coolant system – look no further than Purosil silicone hose.

Reliability & Durability

When Quality Counts?

Silicone 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, and certainly not least, the trend towards more stringent emission requirements result in great heat generation.  Silicone is up to the challenge and increasingly the favoured choice of design engineers.


The basic construction of silicone hose consists of a silicone core or tube, fabric reinforcement and a silicone cover or outer layer.  Purosil silicone hose, unlike some cheaper brands, uses no filler and the tube is made of the same silicone material.  The fabric that is incorporated into the structure is to provide increased rigidity and prevent kinking.  Depending on the use, Purosil silicone hose will also include materials such as polyester, fiberglass, nomex or meta-aramid – each with varying temperature range capabilities.
