An apparatus includes a central core assembly (32a), connected between a swivel (14) on its upper end and the work string (16) below, with the central core assembly having a central passageway (38) therethrough; a first outer assembly (30a) having a central bore for slidably engagement around a portion of the central core assembly. In one embodiment, a second outer assembly (30b) is included, with the second outer assembly having a central bore for slidably engaging around a portion of the central core assembly above the first outer assembly. A pair of opposing transverse bores (54a-54d)) is contained within both of the first and second outer assemblies, corresponding to a pair of transverse bores (40a, 40b) in the central core assembly. The apparatus further includes sleeve members (57a-57d) for aligning the transverse bores; and rams (70a­70d) in the transverse bores for sealing off the passageway in the central core assembly.
