Purosil Announces a New Series of Fluorocarbon Lined Silicone Hoses for the New Generation of EPA Compliant Engines

Corona, CA, March 26, 2008 --(PR.com)-- Purosil’s fluorocarbon lined hoses, using premium DuPont Viton elastomer, are designed to resist diesel fuel combustion byproducts as well as alcohols and fuel additives. The development of Purosil’s fluorocarbon program began in 2005 with the goal to reduce truck operating lifetime costs by preventing failures and increasing maintenance intervals.

The superior barrier properties of Viton fluoroelastomer make Purosil’s FC class of hoses “best in class” for containing crankcase emissions. Viton has five times better barrier properties than fluorosilicone and ten times better barrier properties than chloroprene when used in hydrocarbon containing environments. Purosil’s design also offers an excellent chemical bond between the fluorocarbon liner and the silicone rubber composite structure. Fluorocarbon hoses have a continuous operating temperature of 235° C or 455° F and low temperature capabilities down to -43°C or -45° F. With the combination of aramid fabric, silicone rubber and fluorocarbon liner Purosil products provide exemplary performance and enhanced features.

Purosil manufactures a full array of Coolant, Heater, Turbocharger and Charge Air Cooler (CAC) hoses for all ranges of diesel engines. Purosil products are available through local distributors and heavy duty part outlets throughout North America.

Established in 1958, Purosil serves the Marine, Automotive, Construction, Heavy Duty Truck and Coach Industries through the production of high quality EPDM air intake and silicone hose products. A pioneer in silicone hose manufacturing, Purosil is a leader in the implementation of high strength and heat resistant materials in its products.
