A seal assembly for an annular region defined by a generally planar wall, a first member, presenting a generally flat and annular portion parallel to the wall, disposed in an opening in the wall defined by an annular, axially extending portion of the wall and having a concentric annular rim disposed therebetween, the first member and rim each independently rotatable about a common axis oriented substantially perpendicular to the planar wall, the first member including a circumferential portion generally parallel to the annular wall portion, the rim further including an arcuate hood extending parallel to the rotation axis and secured to a sector of the rim, comprising, in combination: a first annular seal means radially compressed between the annular portion of the wall and the rim, a second annular seal means disposed radially outward of the first member and sealingly engaged with the circumferential portion thereof, the second annular seal means further having a separated portion coincident with the sector of the rim secured to the hood and the separated portion engaged with a radially extending axial end portion of the arcuate hood; and a circular web, having an axially extending portion sealingly secured to the first annular seal and a radially inward extending portion secured to the second annular seal means, the web further including an arcuate opening extending circumferentially around the portion of the annular region coincident with the arcuate hood.
