UNIGRAF® Low Emission Packing for Valves and Fittings

The gland packing is braided and consists of permanently elastic, expanded graphite fibers (c-content >98%), inconel reinforced. The packing is fitted with a special high-temperature waterproofing and a corrosion inhibitor. Through excellent cross-sectional density and special surface texture, very low friction and leakage rates are achieved even under extreme conditions. The compression-moulded packing set meets the TA Luft requirements.
