Claim:
A compression seal assembly, adapted for mounting to a wall having first and second oppositely-facing sides and a hole having a hole diameter, the compression seal assembly comprising: a core member including a cylindrical body defining a longitudinal axis and a flange, the cylindrical body having a first end and a second end, the flange being rigidly attached to the first end of the cylindrical body and having a flange outer diameter that is larger than the cylindrical body but configured to be smaller than the hole diameter, the flange including a bearing surface facing axially toward the second end of the cylindrical body; a first set of external threads on an outer surface of the cylindrical body; a first nut threaded onto the first set of external threads; a split washer surrounding the cylindrical body adjacent the bearing surface of the flange, the split washer being helical-shaped and having first and second ends defining an axial gap therebetween, the split washer having an inner edge defining an inner diameter that is larger than the cylindrical body and an outer edge defining an outer diameter configured to be larger than the hole diameter; wherein the first nut is configured to be positioned on the second side of the wall and the split washer and flange are configured to be positioned on the first side of the wall; wherein tightening the first nut on the first set of external threads compresses the split washer between the flange and first nut, such that the split washer is deflected into a flat condition to apply an axial load on the first nut; wherein the split washer is configured to be passed through the hole from the second side of the wall to the first side of the wall by receiving an edge of the hole in the axial gap and ramping the split washer through the hole.
