A storage tank orifice flexible center mount sealing device comprising a first annular member being substantially flexible having a annular channel, a central orifice and a mating surface, wherein the mating surface is operably configured to be disposed against a wall of a container; and, a second annular member being substantially rigid having a central orifice, wherein the second annular member is disposed in the annular channel and the members are coaxially aligned. The sealing device further comprises a sealing boot disposed on the first annular member, wherein an enclosed environment is defined by the first annular member, the wall and a conduit, which passes through the wall, the central orifices of the first and second members and the sealing boot, wherein mounting hardware used to secure the first and second members to the wall are protected in the enclosed environment and first annular member has a boot mounting area.

What is claimed is: 1. A sealing device for sealing an orifice in a wall comprising: a first annular member being substantially flexible having an outer wall, an inner wall and a mating surface disposed between the outer and inner wall, wherein the inner wall has a height less than a height of the
What is claimed is: 1. A sealing device for sealing an orifice in a wall comprising: a first annular member being substantially flexible having an outer wall, an inner wall and a mating surface disposed between the outer and inner wall, wherein the inner wall has a height less than a height of the outer wall, an annular channel being defined between the outer and inner wall and, a central orifice, wherein the mating surface is operably configured to be disposed against the wall; a second annular member being substantially rigid having a central orifice, wherein the second annular member is disposed in the annular channel and the members are coaxially aligned; and, a sealing boot disposed on the first annular member, wherein an enclosed environment is defined by the first annular member, the sealing boot and a conduit, which passes through the wall, the central orifices of the first and second members and the sealing boot, wherein the second member and mounting hardware used to secure the first and second members to the wall are protected in the enclosed environment, and wherein the first annular member has a boot mounting area disposed on the outer wall, wherein the boot mounting area is operably configured to receive the sealing boot. 2. A sealing device, as recited in claim 1, wherein the first annular member has an alignment tab disposed along the height of the outer wall in the annular channel and the second annular member has an alignment slot, wherein the alignment slot engages the alignment tab when the second annular member is disposed in the annular channel. 3. A sealing device as recited in claim 1, further comprising: a seal disposed on the mating surface. 4. An orifice sealing system comprising: a first sealing device having a first and second annular members, wherein the first member being substantially flexible includes an annular channel, a central orifice, a mating surface and a boot mounting area, wherein the mating surface is operably configured to be disposed against a wall of a container; and, the second annular member being substantially rigid having a central orifice, wherein the second annular member is disposed in the annular channel and the first and second members are coaxially aligned; wherein the device further comprises a sealing boot disposed on the boot mounting area of the first member, wherein an enclosed environment is defined by the first member, the sealing boot and a conduit, which passes through the wall, the central orifices of the first and second members and the sealing boot, wherein the second member and mounting hardware used to secure the first and second members to the wall are protected in the enclosed environment; and, a second device being identical to the first device disposed on a second opposite side of the wall and coaxially aligned with the first device, wherein the first device and the second device seal the first and second side of the wall with the mating surfaces of the devices and the sealing boots of the first and second device are operably configured to form a seal on the wall and a seal on a conduit, which passes through the first device, the wall and the second device when the system is in use. 5. An orifice sealing system as recited in claim 4, wherein the gasket seal is integral to the mating surface. 6. An orifice sealing system as recited in claim 4, wherein the first annular member has a guide tab and the second annular member has a guide slot such that when the second annular member is coaxially aligned with the first annular member the guide slot engages the guide tab. 7. An orifice sealing system as recited in claim 4, wherein the first annular member is made of a substantially flexible material and the second annular member is made of a substantially rigid material.
