Castle® Copperhead™ gasket adhesive contains real copper to improve heat transfer and eliminate hot spots. It seals gasket holes and threaded fittings to prevent leaks, while exhibiting outstanding holding power. Copperhead™ sets up in 60 seconds, and remains tacky for positioning and easy removal. It resists temperatures from -65°F to 500°F and performs well on all types of gaskets.
