A seal for a pressure chamber is provided. The seal is formed by welding a loop of rigid tubular material to the perimeter of the entry of a pressure chamber, conforming to the shape of the parameter. A side wall of this tubing is machined off to produce a continuous slot and a "C"-shaped channel running along the perimeter of the entry. Tubular gasket material is positioned in this "C"-shaped channel to extend partially out of the slot to seal against the door of the pressure chamber. A large diameter gasket may be used, and the interior of the gasket may be pressurized by a vent channel connected with the interior of the pressure chamber. |
