STEEL-UNYTE Pipe Joint, Thread and Gasket Sealer

STEEL-UNYTE is a hard-set, semi-paste, dark gray pipe joint, thread and gasket compound that produces a leak proof seal on all types of metal and plastic threaded connections, flanged gasket fittings, and tanks of all types, including gasoline, tank seams, pumps, electrical transmission equipment, gasoline and diesel engines.  STEEL-UNYTE locks threads yet remains flexible so heavy vibration will not loosen connections.  STEEL-UNYTE seals tightly but allows for disassembly without damage to parts.  STEEL-UNYTE is a safe, economic alternative for many applications where anaerobic sealants are used.    Temperature Range Use: -50°F (-46°C) to 400°F (+204°C).
