Method and apparatus for assembling couplings for transferring fluids

A coupling (10) used to transfer fluid between two conduits includes a seal arrangement that permits an inner sleeve (12) to move axially and angularly without fluid leaking from the coupling. The coupling also includes a pair of coupling members (14, 16) coupled to the inner sleeve, around each end of the inner sleeve. The inner sleeve includes tapered ends (30, 32) sized to receive a seal (120, 122) including a spherical lip (160). Each coupling member includes a tapered end (70, 100) that compresses each seal during assembly of the coupling. The seal spherical lips maintain sealable contact between the inner sleeve and the coupling first and second members.
