About Sealants

Select a sealant that can stretch, contract, and expand enough for your joints.

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.

Heat—Heat cure sealant requires heat of at least 212° F to harden. Above 300° F, the sealant hardens in about 15 minutes. For temperatures below 300° F, it may take up to 4 hours to harden. It requires both heat and a hand tool to unthread.

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.

Non-Hardening Thread Sealants with PTFE

Applicator-Top Can

PTFE provides a slippery surface that keeps threads from binding. These sealants never fully harden, 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.

NSF/ANSI 61—Sealants that meet NSF/ANSI 61 adhere to safety standards for drinking water systems.

VOC-Free—VOC-free sealants won’t harm the environment and comply with LEED Green Building standards. VOC stands for volatile organic compound.
