ABSTRACT:
A split type sealing device for providing high pressure sealing around a cylindrical member such as a tube. The sealing device utilizes a primary flexible split seal ring element and a rigid split back-up ring, which have their splits positioned on opposite sides of the cylindrical member so as to encircle the member. The seal rings are maintained in position against high sealing pressure by a split seal retainer enclosed by mating clamping means, such as a slotted coupling member having an external threaded end and a mating conduit and ring nut. The pressure axial loading on the tube is accommodated by a split clamp ring which clamps the coupling to the cylindrical member, which is usually a tube. The seal device is suitable for sealing against internal pressures of 0-5000 psi.
