FLEX-O-SEAL Universal Joint Gasket

  INTRODUCTION
  Flex-O-Seal is a unique sealing material manufactured from special grade of expanded 100%   pure PTFE by   transforming the fibrous structure by means of a special process. Though very   tough, it is spongy and suited to   almost all flanges, covers and narrow cavities, Its special soft   and flexible character enables it to be the most   ideal seal under pressure without significant cold   flow even on irregular, badly damaged or corroded flange   surfaces. Once bolted this gasket   rarely need to be retorqued.


  PROPERTIES
   Flex-O-Seal recommended temperature - 240 C to 310 C,
                                             PH Range - 0 to14

  No deterioration due to stocking for long time. Resistant to high pressure, non-toxic.

  Not recommended for use against elemental fluorine, alkali metals and strong oxidizing agents.


  APPLICATION
  Flex-O-Seal is safely used in petroleum refining companies even in their offshore operations,   corrosive   chemical processing, food processing, paper mill, marine installation, for glass lined or   fibre glass reinforced   vessels and tank lid sealing, manhole covers, vent pipes, heat exchangers,   pumps or compressors housing   flanges, valves and many more industrial applications where   conventional pre-cut gaskets are not readily   available or unsuitable.


  INSTALLATIONS
  •  The sealing surface must be clean, free from grease and dry to enable the gasket to stick   properly.

  •  The width of the joint gasket is to be determined by the nominal diameter or type of flange.   Selection of a      tentative size of joint gasket would be approx. 1/3rd flange contact width inside   the bolt hole e.g., 7 mm      gasket joint to suit a 20 mm flange width.

  •  Remove the protective foil from the adhesive joint gasket to allow for fitting. Stick the gasket   approx 2mm      away from the bolt hole and press on lightly.

  •  Tighten the lubricated bolts in opposite pairs. Since it is highly compressible only bolt pressure   is required to      seal. The lap joint deforms perfectly to give a reliable seal.

  •  For delicate components such as glass flange the gasket ends can be joined by cutting a step in   each end      of gasket.

  •  FLEX-O-SEAL is easy to install, able to fill severe surface irregularities and reduces inventory   of ready made      gaskets, envelops, etc. It has therefore taken its name as UNIVERSAL JOINT   GASKET.

  •  On irregular or damaged flanged surfaces, it is possible to build up with short length of
     FLEX-O-SEAL.
