Used to seal the valve rod and rotating pump shaft in corrosion-resistant case.
Temperature in use: -180℃ ~250℃
Outside diameter :30mm~200mm
Wall thickness :2mm~5mm
Length :400mm

Expanded Joint Sealant To Top
   Expanded PTFE Joint Sealant is made from 100% pure PTFE.It has excellent anti-acid & anti-alkalis. And well-done tensile strength recovery.Especially,used in food,drink,chemical etc,unneed to make gasket,It can be used easily.                                                                               Pressure :20MPa                                                                                                                    Temperature:-240℃~280℃                                                                                                                      PH range:0-14                                                                                                                     
Expanded PTFE Dalve Stem Packing To Top
     Expanded teflon valve rod filler is another brand-new product of expanded teflon materials. It has all the features for expanded teflon sealing ribbons. It has a round cross section. Used to seal the filler of the valve rod. Automatic moulding, speedy and easy mounting and filling, Like twining a spring, twine it on the valve rod, then press the cover, and the filler will be formed automatically, giving a complete and precisely compact sealing ring without any additional processing.                                                                                                                                                      Pressure working:19.6Mpa                                                                                                   Temperature working:-248℃~315℃                                                                                             Superior filling performance allows to fill up the defects which may create leakages. Superior sealing performance as well.                                                                                                                  Very strong interchangeability: just to have products with several typical specificatinons, they can replace many kinds of similar design-finalized asbetos packing. Ageing-resistant, every to pruchase and store.
