A cylindrical seal arrangement is provided by alternatively disposing a plurality of O-ring seals and cages in a generally cylindrical arrangement. The O-ring seals are generally annular in shape and, in cross section, comprise an inner portion, an outer portion and an connector portion. The three portions of the O-ring seal cross section define annular grooves in the axial surfaces of the seals. Cages are disposed in alternating positions with the seals and each cage is provided with an annular protrusion extending from its axial faces. The protrusions are shaped to be received in the annular grooves of the seals and the O-ring seals and cages are sized to prevent compression of the inner portion of the seal in an axial direction when an axial force is exerted on the cage and seal assembly.
