EATON INTRODUCES NEW ENGINE-SPACE HOSE LINE FOR BIODIESEL AND SYNTHETIC LUBRICANTS

Diversified industrial manufacturer Eaton Corporation has introduced a new line of flexible rubber hose designed for use with biodiesel B2 to B100 in diesel engines, trucks, buses, agricultural vehicles and off-highway applications. In addition, Eaton’s new GH100 ESP™ hose, an Eaton Green Solution, delivers excellent performance with synthetic lubricants used in high-temperature truck transmission oil cooler applications. 

GH100 hose features a hydrogenated nitrile rubber tube, wrapped with aramid/poly braid reinforcement with a polyester abrasion-resistant cover. It is qualified for engine-space use with B2 to B20 up to 150?C and B100 up to 125?C and for transmission oil cooler applications using synthetic lubricants at peak temperatures up to 175?C.

“Biodiesel blends and synthetic lubricants are important aspects of the emerging sustainable energy system and they are going to be increasingly common in the future,” said Alexandra Benz, EMEA product manager – braided and textile hoses for Eaton’s Hydraulics Business. “Unfortunately, these fluids can quickly make ordinary hose products brittle and prone to cracking, and subject them to other forms of premature failure. At temperatures above 100?C, some biodiesel blends above B20 can ‘bake out’ the elastomers necessary to keep hoses flexible. This is a particular problem in vehicles that may see a variety of fuel blends – B5 this week, B20 and higher next week, and so on.
