USH (Piston and Rod Seals)

Available in Fluororubber and NBR.

Used for both piston and rod seals. Compared with special packings the range of application can be limited. For packing material, fluororubber is available for wider temperature range or phosphate ester oil. The USH packings offer a smaller section than UPH packings and can be fitted in the appropriate groove.
