Abstract
The coupling comprises a flexible conduit, a packoff assembly, and a gland nut for compressing the packoff assembly. The conduit passes through a passage in a first member and is secured to the outlet of a second member. The nut is threaded into the passage of the first member to compress the packoff for sealing securement of the conduit to the first member even though the axes of the passage and of the outlet are not coincident. A collar is disposed on the interior end of the conduit to prevent the conduit from blowing out of the passage if the conduit should break or disconnect from the second member.
