Each Seal Guard Wiper consists of two flexible bronze rings which are held in place by a nitrile cushion ring. The cushion ring absorbs side loads and energizes the wiper to maintain close contact with the rod. Particularly suited for hostile environments, seal guard wipers shave off sand, grift, slag, flux, paint, moisture, chips and slivers. Seal Guard Wipers are long-lasting, self-adjusting, and offer low friction. Seal Guard Wipers can be installed in standard Hercules® Sealing Products “ST” or “D” Style grooves by increasing the “F” gland dimension to the “F” Throat Diameter shown.
