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