STM Billet Welding Purge Block for DSM Throttle Body Flange PowerTrain Technology Most importantlyThe STM billet purge clamping block for DSM Evo 1 2 3 throttle body flanges allows us to securely bolt a flange and easily evacuate oxygen while welding to ensure a clean, solid weld and prevent warping. The aluminum block helps draw heat away from the flange while welding and you can bolt the flange securely to the block to prevent warping. Comes with 1 8" NPT threads to accept your purge fittings.
