STYLE 24BB
Expanded PTFE Gasket Tape


 

CONSTRUCTION
Teadit 24BB joint sealant is produced by expanding 100% virgin PTFE into a highly fibrillated structure which is softer and more flexible than regular PTFE and thus conforms easily to irregular and rough surfaces. In addition, the expanded material is easier to compress and exhibits excellent resistance to creep and cold flow. Teadit 24BB gasket tape is supplied as a continuous tape with a self-adhesive backing strip to facilitate easy installation.

APPLICATION / SERVICE
Style 24BB easily seals flanges with rough or irregular surfaces and requires less bolt torque than other gasket materials. It is particularly suited for sealing glass lined and plastic flanges. Made from 100% virgin PTFE, 24BB can be used to seal all aggressive chemicals over the entire 0 to 14 pH range, except for molten alkali metals and elemental fluorine. 24BB will not contaminate or discolor flow media and it is suitable for FDA service.   It has no smell or taste.  It is neither contaminating nor toxic and it fulfills the FDA 21 CFR 177.1550 Perfluorocarbon Regulations.  These industries commonly use 24BB gasket tape:

  • Pulp and Paper
    •
  • Petrochemical
  • Food and Beverage
    •
  • Pharmaceutical
  • Distilleries
  • General Chemical
    •
