EGT Sensor Bung Copper Purge Port & Heat Sink

These pure Copper EGT Purge &Heat Sink Blocks are the perfect solution to fighting warped threads, or overheated EGT sensor fittings during the welding phase of your custom headers. Not only are these copper purge blocks dense, they have exceptional thermal conductivity, helping to maintain heat control on those fine-threaded EGT bungs, and expel the heat harmlessly away from your weld zone. 

These copper purge blocks also incorporate a 1/8" NPT thread on the other end to add a quick-connect fitting for your argon lines, making for quick and effective back purging for your EGT or even flange welding.
