UNIGRAF® Low Emission Packing for Valves and Fittings

  • Article Number: 1376.
  • Material: 1376
  • Profile: PR
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 to fulfill TA Luft requirements.
