JET-LOK III is a two-part, ZINC-FREE epoxy with largely non-metallic fillers that can be used to permanently lock threaded connections under normal operating conditions. Both the handy-pak and kit use a new catalyst for added pot life and durability with lower toxicity and less heat generation making it the optimum choice for any application. It is designed for use on all threaded joints or fasteners where an exceptionally strong and durable bond is required. It is especially useful on drilling tools, casing, and other tubulars where the effective prevention of joint loosening is required.

JET-LOK III is recommended for use on casing, shoes, couplings, and collars; eliminating the need for gas/arc welding. Threadlock Handy-Pak and Kit offer a distinct advantage over welding in that threaded connections may be broken out by heating to 550°F (288°C). This product is also excellent for any application requiring a strong, permanent bond that has high vibration resistance. Being free of zinc enhances its durability in wet services.
