Thread Sealants for Oxygen Systems


Tube	Jar

Completely free of oil and chemically inert, these sealants are safe to use with wet and dry oxygen systems. They contain PTFE, which provides a slippery surface that keeps threads from binding. These sealants are non-hardening, remaining pliable enough to self-heal and stop leaks before they start, so they’re often used in high-vibration applications that could cause standard thread sealants to fail. Since they have low locking strength, these sealants can be adjusted without tools.

Tube—The sealant in a tube is a good alternative to thread sealant tape—like tape, it forms PTFE strings between tightened threads, but excess material liquefies, so it won’t clog system components downstream.

Reusable Non-Hardening Thread Sealants for Fine Threads

Formulated to flow into small spaces, use these sealants between fine threads. Threads coated with these sealants can be installed multiple times without recoating. They have low locking strength, so they prevent threads from loosening due to vibration and can be adjusted without tools. They meet NSF/ANSI 61 for use with drinking water.

Thread Sealant Tape

Made of PTFE, this tape has a slippery surface that keeps threads from binding to make parts easy to assemble.

ePTFE with Graphite—ePTFE tape with graphite creates a better seal between threads than plain PTFE tape, which helps prevent fluid and gas leaks. The graphite attaches to the PTFE, so this tape does not emit harmful VOCs.

High-Temperature Thread Sealants

These sealants have high locking strength, so they work in demanding applications, such as securing mounting studs in motor housings. They also withstand applications with large temperature swings.

Room Temperature—Room-temperature cure sealants must be mixed with water for use; they harden as the water evaporates. Mix about five parts powdered-sealant to one part water to form a thick consistency similar to peanut butter. Hardening can be accelerated with heat; do not heat to above 200° F. They require a hand tool to unthread.

1,000° F Maximum Temperature—1000° F max. temp. sealants expand as they harden.

1,500° F Maximum Temperature—1500° F max. temp. sealants are for use on cement-lined pipe joints prior to welding. The heat from the welding torch helps them begin to harden.
