Description
Overview
The Fiberglass Cover Stainless Steel Hollow Core Tadpole Gasket is a highly compressible thermal sealing profile designed for industrial oven doors, furnace access panels, ducts, dampers, thermal enclosures and other equipment requiring flexible sealing around uneven or changing gaps. The gasket combines a woven fiberglass outer cover with a hollow stainless steel core to produce a lightweight, compressible bulb that deforms under closing pressure and recovers after load release.
Construction and Key Features
The product uses a bulb-and-tail configuration where the hollow metallic bulb provides compression sealing and the flat fiberglass tail provides a mounting/retention section.
Component / Construction / Function
Component | Construction | Function
Outer Cover | Woven Fiberglass Fabric | Provides the flexible external thermal textile layer
Internal Core | Stainless Steel Hollow Core | Creates a resilient and highly compressible bulb
Bulb | Fiberglass Wrapped Hollow Metal Core | Forms the primary compression sealing area
Tail | Fiberglass Fabric | Provides the mounting and retention section
How It Works
The hollow core changes the mechanical behavior of the tadpole bulb by containing an open central area inside a metallic structure. Under closing pressure the bulb collapses inward with comparatively low force (higher compressibility), adapting to variations in sealing gaps. After load removal the stainless steel core aids recovery toward the original profile.
Typical Advantages
Woven Fiberglass Outer Cover
The external fiberglass fabric contains and protects the hollow metallic core while forming the flat mounting tail. Fiberglass offers flexibility, dimensional stability and resistance to elevated temperatures and allows the gasket to follow corners and door frames without rigidity of a fully metallic seal.
High Temperature Capability
Comparable fiberglass cover and stainless steel hollow core constructions are commonly specified for service temperatures around 1000°F / 538°C. Actual usable temperature depends on fiberglass grade, stainless steel core construction, stitching material, compression condition and surrounding atmosphere. Continuous and peak temperature limits and exposure duration should be confirmed for high temperature applications.
Comparisons and Selection Guidance
Hollow stainless steel cores provide higher compressibility and generally lower closing force than solid stainless steel cores. Hollow cores are softer and more collapsible, offering very good gap accommodation, while solid cores provide firmer structure and controlled compression. Compared with fiberglass rope cores, hollow stainless steel cores add metallic resilience while maintaining flexibility.
Customisation Options
Manufactured in custom bulb diameters, bulb heights, tail widths, overall profile dimensions and finished lengths. Hollow core construction and mesh density can be varied to tune compression force, recovery behavior, bulb firmness, mechanical durability and resistance to repeated cycling. Single-knit and reinforced hollow core options are available to adjust compression characteristics and durability.

Typical Advantages
- High compressibility
- Lower closing force compared with many dense core constructions
- Good conformity to uneven surfaces
- Metallic reinforcement inside the bulb for resilience
- Useful recovery after repeated compression
- Ability to accommodate variations in sealing gap
- Suitable for doors, covers and removable panels
