Blue Monster Yellow Gas PTFE Thread Seal Tape

Blue Monster™ Gas Guard PTFE Thread Sealing Tape – Engineered for Gas Line Safety and Performance

Blue Monster™ Gas Guard PTFE Thread Sealing Tape is a high-density, premium-grade thread sealant engineered specifically for gas line applications. Manufactured by Mill-Rose, this maximum-density PTFE tape is designed to outperform conventional tapes, delivering safe, reliable, and long-lasting seals in critical gas systems.

What sets Blue Monster Gas Guard apart is its non-stretched manufacturing process. Unlike many other thread sealing tapes, which are stretched to appear longer and thinner, Blue Monster retains its full density by avoiding stretching altogether. This results in a thicker, more robust tape that creates an effective seal using fewer wraps, eliminates shredding or stringing during application, and minimizes waste.

Purpose-Built for Gas Lines

Color-coded in high-visibility yellow, Blue Monster Gas Guard is easily recognized and accepted by gas fitters, inspectors, and regulatory bodies worldwide. It’s ideal for sealing natural gas, propane, butane, and other fuel gas lines, providing a dependable solution in both residential and industrial settings.  DO NOT use in Oxygen applications.
