3/4" x 1000" Gas Guard PTFE Thread Seal Tape

Blue Monster 70827 Gas Guard PTFE Thread Seal Tape – High-Density Yellow Tape for Gas Service

The Blue Monster 70827 Gas Guard Thread Seal Tape is engineered for sealing threaded connections in natural gas, propane, butane, and other fuel gas systems. Manufactured from 99% pure PTFE with a high-density composition, this tape is specifically designed for use in gas piping installations where durability, chemical resistance, and code compliance are required.

The yellow color conforms to industry identification standards for gas-rated thread sealants. Its full-density, non-stretched construction improves sealing performance by maintaining uniform thickness and reducing cold flow under pressure. The tape also acts as a thread lubricant and anti-galling agent, helping to prevent seizure and thread corrosion over time.
