RS

RS Buffer Seal provides effective leakage sealing for a wide range of heavy-duty cylinder applications. Its two-piece design features a PTFE Seal and Nitrile (NBR) energizer. When typically used in conjunction with a polyurethane U-cup, RS Buffer Seals will reduce the high pressure imposed on the primary U-cup seal. 

The RS Buffer Seal is recommended for light and medium-duty cylinder applications requiring low temperature and low pressure.
