Abstract : An investigation was made to find a suitable material, unaffected by Oronite 8515, to seal pipe threads at pressures up to 5,000 psi and exposure to 350 F. Several commercial thread sealing compounds and thiokol type sealants were tested and each failed. The only suitable seal was obtained by wrapping a single thickness of Permacel teflon tape around the male threads before joining the fittings. In joining the fittings the tape is cut into rings inside the threads; and therefore there is the possibility of some of the rings entering the system. (Author)
