DESCRIPTION
The D-STXE wiper is used in applications with a severe side deflection. The radius wiper lip reduces rod seal leakage with equivalent ingression resisteance to a sharp lip wiper. O-ring must be installed for proper performance. 
The shell is molded in polyurethane with a Nitrile energizer, ensuring flexibility for installation and performance.
