Double action piston seal TDE is tradition- ally produced in fabric reinforced rubber combinations used in intermediate to very high stress application. Larger tolerances can be chosen by using NBR fabric com- binations on one hand and radial pre stressing on the other. This material com- bination avoids split extrusion due to high impact pressure. TDE 35 : NBR fibre reinforced : up to 50 MPa (500 bar) : reciprocating to 0.5 m/s : -30 to +110 °C Piston Sea l Material Operating pressure Velocity Temperature Special Features: Three part composition from fibre and elastomer reinforced combination and POM slide ring. Assembly on multiple part pistons. Assured sliding due to the type of closed sealing component and slide rings on both sides. Good resistanc of pressure and vibration. Reduced stick slip tendency due to fabric component on dynamic side. Modified NBR resulting in high friction resistance. Also available in FPM material. Has a small total width.
