Graphite Electrode Nipples (3TPI / 4TPI, T3L / T4L) are precision pins that connect graphite electrodes in electric arc and ladle furnaces. Made from high-quality needle coke and graphite, they are carefully machined and graphitized for accurate threads, strong strength, and reliable conductivity. With standard 3TPI and 4TPI threads, these nipples ensure tight connections, good load-bearing, and steady performance in high temperatures and currents. Their low resistivity, resistance to oxidation, and sturdy build help extend electrode life and boost furnace efficiency.
