Fluid-tight flexural joint

A fluid-tight flexural joint for enabling a first portion of a rigid fluid flow conduit to flex with respect to a second portion thereof to accommodate off-axis conduit connections, said joint comprising:

• a generally spherical knuckle projecting axially from one end of a first conduit portion, said knuckle defining a fluid flow channel extending therethrough in axial alignment and fluid communication with the first conduit portion;
• a knuckle housing threadably engaging an end portion of a second conduit portion, said housing being in fluid communication with the second conduit portion and disposed about and in sealing engagement with said knuckle so as to define a continuous fluid passageway extending through said first and second conduit portions and said knuckle whereby the first and second conduit portions are coupled together in a flexible fluid-tight sealing engagement.

• a conduit extension defining first and second end portions, said first end portion being configured for engagement with a first conduit portion;
• a generally spherical knuckle projecting axially from said second end portion of said conduit extension, said knuckle and said conduit extension defining a fluid flow channel extending axially therethrough;
• a knuckle housing threadably engaging an end portion of a second conduit portion, said housing being in fluid communication with the second conduit portion and disposed about and in sealing engagement with said knuckle so as to define a continuous fluid passageway extending through said first and second conduit portions, said knuckle and said conduit extension while allowing for rotational and pivotal movement of said conduit extension with respect to said second conduit portion whereby said first and second conduit portions are coupled together in a flexible fluid-tight sealing engagement.
