Overview
The Clip-on Fiberglass Oven Door Gasket with 304 Stainless Steel Wire Core is a resilient high-temperature door seal designed for ovens, dryers, furnaces, thermal enclosures and OEM heating equipment. It combines an E-glass fiberglass overbraid, a knitted 304 stainless steel hollow wire core, and formed stainless steel mounting clips. The fiberglass exterior forms the flexible heat-resistant sealing surface, while the hollow knitted metal core provides the compressible structure and spring-back required for repeated door opening and closing.

Construction
E-Glass Fiberglass Overbraid
The outer surface consists of braided E-glass fiberglass yarn. The braided textile layer creates a flexible outer sealing surface around the metallic core and allows the gasket to follow straight sections, curves and corners around a door frame. The braid structure can be adjusted according to required gasket diameter, density and finished construction.

Knitted 304 Stainless Steel Hollow Core
Inside the fiberglass braid is a tubular core manufactured from knitted 304 stainless steel wire. Unlike a solid rope core, the hollow knitted metal structure can deform when the door closes and recover when the compression load is released. This internal structure helps provide:

• Controlled gasket compression
• Elastic recovery after door opening
• Profile support
• Repeated compression capability
• Flexibility around corners
• Dimensional stability during installation

The required core construction should be selected according to the sealing gap, required closing force, gasket diameter and equipment geometry.

Formed Stainless Steel Mounting Clips
Individual formed stainless steel clips are incorporated into the gasket for mechanical attachment. The clips engage corresponding mounting holes in the door, frame or enclosure structure. For OEM production, the clip arrangement can be developed around equipment layout rather than relying on fixed universal spacing. Custom variables can include:

• Clip spacing
• Clip quantity
• Clip position
• Clip orientation
• Corner clip position
• Distance from gasket ends
• Door or frame hole pattern

This construction makes the gasket suitable for both new OEM equipment and engineered replacement applications.

Clip-On Gasket vs Conventional Fiberglass Rope Gasket
A conventional fiberglass rope gasket is normally installed in a groove, channel or other retaining structure. A clip-on oven door gasket incorporates mechanical attachment points directly into the gasket construction so it can be fixed to doors or frames with matching mounting holes. The knitted stainless steel hollow core yields a different compression response from a conventional solid fiberglass rope, so selection should be based on both sealing requirements and equipment mounting system.
