Silex peroxide cured silicone rubber tubing is stocked in translucent Shore A hardness with inner diameters from 30-60mm as standard, but can be produced in almost any size or colour, in a wide range of hardnesses. 

Peroxide cured tubing offers a most cost-efficient alternative to platinum cured tubing; however the peroxide curing process produces by-products that make it unsuitable for some applications. Check with our Sales Team for more Info.
