Perma-Seal™ terminals and splices are rugged, environmentally sealed connectors that will insulate, seal, and protect connections from physical abuse and abrasion. The insulation is a propriety polymer called NiAc™ which provides long lasting, moisture proof connections even in the most hostile environments. The NiAc™ polymer can withstand water, salt, corrosion, and heat all of which can cause serious problems to conventional, unsealed connections.
