Mill-Rose 70885 - 1/2" x 1429" BLUE MONSTER THREAD SEAL TAPE

Blue Monster PTFE Thread Seal Tape is a thicker, denser, general-purpose thread seal tape that comes in a monstrous 1,429" roll. Thats 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.

Blue Monster thread sealing tape is manufactured from PTFE resin, a polymer consisting of recurring tetrafluoroethylene monomers whose formula is (CF2-CF2)n. It is inert and compatible with a very wide range of materials. Use Blue Monster on threads made from galvanized steel, iron, brass, copper, aluminum, stainless steel, polyethylene, polypropylene, PVC, CPVC, ABS, fiberglass and more.
