Anti-Seize Gas Line Sealant Tape

Anti-Seize 46350A is a yellow PTFE thread sealant tape designed for gas piping installations. It suits plumbers, HVAC technicians and maintenance crews who need a reliable seal on threaded connections up to 3/4 inch diameter. The tape meets the POLY-TEMP (R) GAS (XHD) series specification for fuel gas service.

Replaces basic white PTFE tape and liquid pipe dope

Standard white tape is often too thin for gas pressures and can shred during assembly. This heavier XHD grade resists tearing and handles up to 2,000 psi gas pressure and 10,000 psi liquid pressure. The upgrade is worth it whenever code or the installer calls for a yellow gas-rated tape with higher linear density.

PTFE tape temperature and pressure limits

The material operates from -400 to 550 degrees Fahrenheit, covering cryogenic to high-heat piping. Maximum linear density is 1.5 g/cc and minimum is 1.2 g/cc, which defines the tape thickness range. It is not intended for oxygen service or for threads larger than 3/4 inch.

Questions about this item

Does the 3/4 in width fit standard gas pipe threads up to 3/4 in diameter?

Yes, the tape is rated for maximum thread diameter of 3/4 in and the 3/4 in width covers those threads fully.

How do I wrap the POLY-TEMP GAS XHD tape so it seals without bunching?

Start at the second thread, wrap clockwise with slight tension, overlapping each turn by half the width; the 1.2 to 1.5 g/cc density prevents stretching if you keep tension even.

When should I replace the yellow tape on a gas line that sees temperature swings?

Re-tape whenever the joint is broken; the tape remains stable from -400 to 550 Degrees F and handles 2,000 psi gas pressure, so it lasts until the connection is disturbed.
