The STM billet purge/clamping block for RS3/TTRS exhaust mid pipe 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. These are the same purge blocks our fabricators use and they are made in-house at STM.

What is Weld Purging?
Weld purging is the process of evacuating oxygen from a pipe, tank or chamber using gas such as argon or nitrogen. This seals off oxygen from entering the weld pool - which can cause poor quality and loss of corrosion resistance.
