An oven door stretch gasket which comprises an extruded length of silicone rubber having a relatively short hooked metal insert adhered to the interior of the ends thereof. The insert is adhered by means of room temperature vulcanizing silicone rubber cement. The hook ends are adapted to be engaged in apertures which are provided at the corners of an oven chamber in a stretching action, the openings being spaced apart somewhat more than the unstretched distance between the hook ends. To install or remove the gasket it must be stretched. The invention herein is concerned with a structure which will provide a more tenacious adherence between the insert and the length of gasket.

An oven door seal of elastomeric material having metal hooks at the ends for mounting it on the door, which hooks are permanently fastened to flanges on the elastomeric material by a crimping operation.

A pneumatic gasket adapted to be used in an oven door construction in which the door is adapted to be sealed to an oven surface when the door is closed. The gasket is an elongate extensile elastomeric member with first and second sections. The second section is a hollow member which is sealed at its ends or at other desired locations, the space between each of these sealed points forming a hollow air chamber of substantial volume which will expand when exposed to the temperatures produced by an operating oven. The second section may be sealed to produce the air chambers by adhesives such as a room temperature vulcanizing adhesive or by mechanical means. The second section may be a coextensive flap hingedly secured along one edge of the first section. The gaskets have means connected to the first sections removably to secure them to the oven surface to hold them in place between the oven and the door, while allowing them easily to be removed to replace them or to clean the oven.

A clipless door seal for oven doors or the like including a sealing element having a length greater than its width, a pair of resilient elongated flanges depending from the outer surface of the sealing element and running substantially the entire length of the sealing element, and at least two resilient retaining darts for securing the door seal to an oven door surface. Generally, the door seal is positioned onto an oven door or the like which has at least two apertures for securing the door seal to the door surface. The darts are positioned through the apertures for securing the door seal onto the door wherein said elongated flanges provide bias to permit said darts to fully pass beyond the wall forming the door surface.
