Applications //
3R 705 is a well lubricated, medium-hard packing with very low frictional characteristics, which assure minimal shaft wear. The ramie yarn is rot and mildew resistant, making the packing ideal for marine use, handling cold water, salt water and cold oils. In the marine industry it is commonly used in stern tubes, rudder posts, and tail shaft liners. This style packing is also used in the pulp and paper, water/wastewater, and mining industries where a softer packing is desired for lower pressure hydraulic applications.
