Apply this thread sealant stick without a mess. It contains PTFE, which provides a slippery surface that keeps threads from binding. Since the sealant is anaerobic, it doesn’t begin to harden until coated surfaces are threaded together, blocking exposure to air. It has low locking strength, so it prevents threads from loosening due to vibration and can be adjusted without tools. It meets NSF/ANSI 61 for use with drinking water.

Much thicker than sealants for fine threads, these sealants bridge the gaps between coarse 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.

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.

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.

Wind this multifilament cord into the grooves of tapered pipe threads to quickly create a seal. It can be applied to metal pipe up to size 4 NPT and plastic pipe up to size 1 1/2 NPT. The container includes a built-in cutter for fast application. After tightening, pipe can be loosened up to an eighth of a turn without leaking. Sealant meets NSF/ANSI 61 for use with drinking water in systems up to 180° F.

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.

Threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked.

243 secures aluminum, stainless steel, titanium, and plated fasteners without a primer.

Mix these two-part surface fillers together to repair leaks and cracks as well as to rebuild rough spots in metal. The size listed is the combined total of the two parts.

NSF/ANSI 61 surface fillers meet safety standards for use with drinking water.

Surface fillers in a stick have a resin on the outside and a hardener on the inside. Cut the desired amount from the sticks, knead to a uniform color to mix, and press into place.
