3R 771
HIGH TEMPERATURE NON
ASBESTOS VALVE STEM PACKING

ISO 9001 : 2000 Certified
3R 771 is a proprietary braid-over-core construction, using a special high temperature inconel reinforced fiber and a non-hardening core. The packing is impregnated with a high temperature resistant compound and coated with fine particles of graphite to act as a surface lubricant. 3R 771 is also treated with an aiding material to alleviate electrolytic action.

Applications //

3R 771 is a firm, high density, non-asbestos packing. It can handle steam, most chemicals, mild acids and alkalies. It is excellent for use in steam turbines, high temperature motor-actuated slide valves and in high pressure/high temperature valving in general.
