Blue Monster PTFE Thread Seal Tape is a thicker, denser, general-purpose thread seal tape that comes in a monstrous 1,429" roll. That’s 5 times more tape than conventional rolls of low-density thin tapes. Fewer wraps are necessary to affect a leak-proof seal and it applies easily. No waste and no re-taping make sealing joints a breeze. Now available in a smaller roll, Mini-Monster PTFE thread sealant tape.
