About Sealant Flexibility

Non-Hardening Caulk

Also known as thumb-grade caulk, this forms a non-hardening, moisture-resistant seal that remains pliable.

Butyl rubber has a sticky, gummy consistency.

Butyl mastic has a clay-like consistency.

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.
