ABSTRACT:
A pipe cap assembly with embodiments which are capable of use over a very wide temperature range and which may be cycled through temperatures varying widely from the ambient assembly temperature and also over a wide range of pressures without the need to be retightened. The embodiments of the invention include a pipe cap for sealing a pipe comprising a hollow fitting member with a first end and a second end and an annular tapered ridge extending from the first end of the first hollow fitting member and threads to attach the hollow fitting member at the first end thereof to a pipe. A hollow sealing member further comprises the invention having a first end and a second end, the first end of the hollow sealing member forming an annular taper channel configured to compliment the shape of the annular tapered ridge and to sealingly engage the annular tapered ridge of the hollow fitting member such that the hollow sealing member substantially retains its original configuration when the annular tapered channel receives the annular tapered ridge. A cap member further comprises the invention, wherein the cap member engages the second end of the hollow sealing member.
