A siding die utilizes a lip defining the orifice and provided with a pair of lip members with mating formations at their opposite ends so that the lip members are forced together when end screws bridging the lip members are tightened. The formations include inclined surfaces of respective noses which transform force applied longitudinally to the lip members to transverse sealing forces holding sealing surfaces of the lip members together on each end of the orifice.
