LOX-8® Paste: Nothing Will Stop It from Sealing a Joint – Not Even Harsh Acids, Caustic Bases, or Extreme Temperatures

LOX-8 Paste is a PTFE thread sealant and lubricant that is specifically formulated for use in wet, high-temperature environments as well as in extreme low-temperature cryogenic environments. LOX-8 is approved for use with liquid and gaseous oxygen, and is immune to the effects of dozens of acids or bases that destroy other thread sealants. In short, it is the toughest thread sealant you can buy.
