Got a new pipe from FMF today, it was supposed to have 2 orings to seal it at the flange...It had only one in the baggie...well Im a impatient fella and am looking for something to just get it done...beside those orings usually dont last me that long. The metal sealing ring fell out in 3 pieces too I was thining of trying some woodstove door sealing rope stuff and slabbing on some high temp RTV.
