Flouroelastomer. Operating Temp 400 F Temperature to 600 F Intermitenly. Widest Range of Chemical Compatability of any Rubber. Severe Chemical Peristaltic Pump Tubing. Durometer 75 Shore A. Made of 100 percent pure Viton, a high performance synthetic rubber. Excellent temperature resistance, from -40 F to 400 F continuously; 600 F periodically. Offers the widest range of fluid and chemical resistance of any commercial rubber. Excellent resistance to oils, fuels, lubricants, and most mineral acids, also resistant to many aliphatic and aromatic hydrocarbons such as carbon tetrachloride, benzene, toluene, and xylene. Excellent resistance to environmental exposure such as sunlight and ozone. High Quality Hytrel Tubing with Silicone Ends. This works with all machines that do not have a pressure line tube in the circuit. This hose is not compatible with the Knightstar 420S, 420E, or 330. All of these machines have hoses with built in pressure sensing tubes.

Silicone rubber is able to resist extreme temperature variances, from -150 Deg F to 500 Deg F (-101C to 260C), and has natural translucent color for visual flow. Resists U.V. ozone gases, moisture and temperature. Resilient, stretchable and resistant to compression set and is odorless, tasteless and inert. Silicone is extremely resistant to ozone and corona concentration over long time periods. The outstanding property of silicone is its great resistance to temperature extremes. This, in addition to good electrical properties, along with the ability to self -extinguish typically within 3 -8 seconds, make silicone an excellent choice for appliance and computer applications. Contains no sulphur or other acid producing chemicals so it does not cause staining, corrosion or deterioration of other materials it contacts. Standard barbed fittings and lined hose clamps are recommended for most applications. Durometer reading: 50A. Specific Gravity 1.14. Elongation at Break 375 Percent. NSF 51
500 Deg. Max. UV and Ozone Resistant.
