Anti-Seize 46135 Thread Sealant Tape

This white PTFE tape measures 1/2 inch wide and 520 inches long for general-purpose thread sealing. It suits plumbers and maintenance technicians who need a reliable seal on pipe connections up to 1 1/2 inch diameter. The POLY-TEMP HD series handles liquids at 10,000 psi and gases at 2,000 psi. Density ranges between 0.9 and 1 g/cc for consistent coverage.

Build integration and system fit

The tape wraps directly onto clean male threads without paste or compound, freeeing up time during assembly and disassembly. It requires no curing period, so the joint can be pressurised immediately after tightening. The roll fits standard tool pouches and works with steel, brass, copper and plastic fittings. No additional sealant or lubricant is needed for the listed pressure ratings.

Sustained load behaviour

Operating temperatures from -400 to 550 degrees Fahrenheit mean the tape remains stable through freeze-thaw cycles and high-heat steam lines. It does not harden, crack or cold-flow under continuous vibration or thermal expansion. The seal maintains integrity at maximum rated pressures for the service life of the joint. Buyers needing oxygen-service certification or tape wider than 1/2 inch should verify specifications separately.

Questions about this item

At what temperature does the tape reach its upper limit during continuous high-heat exposure?

The tape is rated for a maximum operating temperature of 550 Degrees F, so sustained use above that level exceeds its design limit.

How does the tape behave when left under pressure and heat all day?

It remains stable up to 10,000 psi for liquids and 2,000 psi for gases at temperatures between -400 Degrees F and 550 Degrees F.

What pipe thread size must already be present for this 1/2 in wide tape to seal correctly?

The tape is intended for threads up to 1 1/2 in diameter, so the fitting must fall within that range.
