Style HSU u-seals are precision molded from 90 Dureometer Buna-N rubber or 90 A Fluorocarbon (suffix 'V') - 90 Duro Rubber for abrasion resistance and Fluorocarbon for heat resistance. These seals are commonly found in industrial cylinders, as piston, rod and cushion seals. -
Molded in Nylon with a rubber energizer this style absorbs the shock of pressure spikes and relieves back pressure by way of slots on the pressure side of the energizer

These piston seals provide bi-directional, low friction sealing with increased stability and superior leakage control. The square cut energizer provides low pressure sealing and eliminates backside leakage. This seal also effectively seals between different fluids on each side of the piston seal, making gas/liquid sealing combinations possible.

SG - 'Seal Guard' Metallic Rod
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 HerculesÂź Sealing Products âSTâ or âDâ Style grooves by increasing the âFâ gland dimension to the âFâ Throat Diameter shown.SEAL INFORMATION MATERIAL 660 BRONZE
