A local welding outlet sold me a pair of flashback arrestors with a 9/16th thread. I explained it was for a Port a Torch cart and when I got home the threads did not match. Is it safe to add the thread adaptors to accommodate the 3/8th thread I need? The store charges a re-stocking fee and their prices are a bit cheaper the local Praxair store in town.
