High Temperature Anti-Seize Lubricant and Thread Sealant

Jomar's Hi-Temp is a copper based anti-seize lubricant and thread sealant. It produces a permanent leak-proof metallic seal under pressure, yet prevents seizing, galling, freezing, and tearing, even under extreme conditions. It is lead free, non-corrosive, nontoxic, and will not harden in can.


Do not dilute. Stir well before using. Clean mating surfaces. Brush onto mating surfaces. Make up joint and apply appropriate torque if required. Keep container closed at all times when not in use to avoid contamination.
