Abstract
A reducer seal assembly for providing a fluid-tight through-wall fitting. The seal includes a substantially rigid tubular supporting member having a flange extending radially about one edge. The flange and the interior of the supporting member are covered with resilient material. The supporting member is externally threaded so that a nut may be joined thereto. The resilient member coating the flange of the support member may be curved to conform to a convex wall surface. The resilient member extends beyond the supporting member for connection about a conduit extending through the wall. The assembly is connectable to a wall by first inserting the support member through a wall from the exterior side and then the nut is applied to the threaded portion of the support member to the extent that the resilient coating has compressed to form a fluid-tight seal between the coating and the exterior wall surface. A hose clamp is applied about the resilient material extending through the support member for providing a compression fitting against the conduit.
