Two symmetrical pieces form an escutcheon that seals the gap between a pipe or conduit and the surface through which it penetrates and supports the pipe or conduit. The device is surface mounted with threaded mechanical fasteners which can be adjusted to vary the compression of the sealing gaskets. The escutcheon can be installed without requiring any manipulation of the pipe or conduit. The escutcheon can be removed and reinstalled repeatedly without any degradation in function.
