About Sealant Flexibility

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.

Drip-Free Thread Sealants with PTFE

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.
