Pipe Thread Sealant for Industrial Piping

Anti-Seize Technology 14003 is a non-hardening pipe thread sealant supplied in a 3 fl oz tube. It is formulated with TFE for use on brass, cast iron, copper and stainless steel threads up to 2 in diameter. The off-white compound suits maintenance engineers and plumbers sealing fuel, LP gas, oil, steam and water lines in industrial and commercial systems.

Temperature and pressure headroom

The sealant remains effective from -50 Degrees F to 500 Degrees F, giving wide thermal headroom for steam and chilled-water circuits. It withstands 10,000 psi for liquids and 2,000 psi for gases, covering most high-pressure hydraulic and pneumatic installations. The non-hardening cure allows disassembly without damaging threads, though it is not intended for permanent structural bonding or extreme vibration environments.

NSF and UL listed sealing standard

This product meets NSF standard 128341 and carries UL Listing, confirming suitability for potable water and safety-critical piping. The TFE-based formula resists chemical attack from the listed fluid types but is not rated for aggressive solvents or molten alkali metals. Buyers needing certification for oxygen service or specific pharmaceutical clean-room standards should verify compatibility before specifying.

Questions about this item

Will this sealant work on the brass and copper fittings I already have in my system?

Yes, it is formulated for use with brass, copper, cast iron and stainless steel threads up to two inches in diameter.

How can I confirm the joint is sealed correctly once I have applied it?

The non-hardening compound remains pliable so you can pressure-test the line up to 2,000 psi for gas or 10,000 psi for liquid without the seal cracking.

Does the 3 fl oz tube come with a brush or do I need a separate applicator?

The product is supplied in a squeeze tube that dispenses the off-white paste directly onto the threads.
