Non-Hardening High-Temperature Thread Sealants
Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start. They have low locking strength, so they can be adjusted without tools.

High-Temperature Thread Sealants
These sealants have high locking strength, so they work in demanding applications, such as securing mounting studs in motor housings.
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.
1000° F max. temp. sealants expand as they harden.
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.

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start. They have low locking strength, so they can be adjusted without tools.
To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.
Sealants that cannot be sold to the regions listed exceed local regulatory limits on VOCs (volatile organic compounds).

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