💡 How do sealed butt splice connectors keep power steady during rough off road driving? These handy terminal joints route electricity safely while absorbing frame flex without failing. - Soft drawn copper strands flatten uniformly under crimp pressure to eliminate resistive hot spots - Meltable polyolefin lining flows into bare wire gaps creating a permanent waterproof airlock - Rigid nylon shank absorbs constant chassis bouncing so your wire pairs never chafe together - Heat stabilized polymer body resists melting when routing near exhaust manifolds or headers
