About Sealant Flexibility

About Structural Adhesives

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.

Threadlocker Tape

Wrap this no-mess tape around threaded fasteners up to 30 days before installation. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes, and cadmium and zinc coatings.

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ORDER HISTORY after your order ships.
