It protects threads from corrosion, cures in about 15 min, and handles temperatures from 65 to 300°F. A pin-point applicator puts gel precisely where needed, even in hard-to-reach and vertical applications. Unlike liquid threadlockers, the gel does not drip or leak. And it does not need to be forced into threads like solid-stick methods. Medium-strength Blue Gel locks 0.25 to 1.0-in. nuts and bolts and disassembles with normal hand tools. High-strength Red Gel handles heavy-duty 0.38 to 1.0-in. high-stress nuts and bolts and eliminates the need for mechanical locking devices such as lock washers, serrated flange nuts, and ribbed flange bolts. Removal may require heat or special tools.
