2、MIDE 12 (PA12) COVER, ETFE TUBE, WSS-M98D33-A6 ETFE TUBE, HIGH PRESSURE, FUEL/ALCOHOL RESISTANT, CONDUCTIVE, LOW PERMEATING 1. SCOPE This specification defines a Multilayered Tubing with a conductive inner layer. The construction has low permeation rates and good resistance to fuel/alcohol blends. 2

3、. APPLICATION This specification was released originally for flexible fuel lines requiring low permeation and electrical conductivity. The maximum working pressure should not exceed 690 kPa. Long term continuous operating temperature should not exceed 90 C and maximum intermittent temperature should

4、 not exceed 115 C. These lines will meet the requirements of the US market for both reformulated and flexible fuels. 3.
