Metal gasket

Product overview
The stainless steel wire mesh jacketed fiberglass oven and kiln door gasket is a high-temperature sealing solution combining a flexible fiberglass sealing body with a knitted stainless steel outer jacket to provide thermal sealing plus surface protection against mechanical wear.

Construction
The gasket comprises two primary functional layers:

• Fiberglass sealing body — provides the flexible thermal sealing element
• Knitted stainless steel wire mesh outer jacket — protects the sealing surface from abrasion and repeated contact

Internal core constructions can be tailored to required profile, compression behavior and equipment design.

Stainless steel wire mesh outer jacket
The knitted stainless steel mesh is applied around the fiberglass core to create a flexible protective layer without turning the gasket into a rigid metal seal. The jacket protects against:

• Repeated rubbing and abrasion
• Sliding contact and door movement
• Metal-edge and installation wear
• High-cycle opening and maintenance handling

Why add a metal jacket to a fiberglass gasket?
The metal jacket separates the textile sealing body from direct mechanical contact, producing a gasket that combines:

• Thermal sealing from the fiberglass core
• Surface reinforcement from the stainless steel wire mesh

Correct construction depends on operating temperature, sealing gap, movement, compression and abrasion conditions.

Flexible knitted metal construction
The external knitted metal layer follows gasket geometry and allows installation in:

• Straight sealing channels
• Curved sections and large-radius corners
• Door perimeters and furnace access openings
• Kiln door sealing channels and custom geometries

Internal gasket construction options
The stainless steel jacket can be combined with different internal cores according to application needs:

• Fiberglass rope core — flexible and conformable
• Braided fiberglass core — denser profile definition
• Knitted textile core — softer compression for conformity
• Stainless steel mesh supported core — metallic support for resilience

Round and custom profiles
Round profiles are common; custom profiles can be developed. Key dimensions: outside diameter, profile width and height, channel width and depth, closed gap, required compression and overall length. Provide drawings for non-standard profiles.

Designed for high-cycle door applications
Suitable for equipment opened and closed frequently; designed to withstand repeated compression, rubbing, sliding and rough channel edges encountered in industrial ovens and kilns.

Typical applications
Wire mesh jacketed fiberglass gaskets are typically used for:

• Industrial oven doors
• Kiln doors
• Furnace doors and heat treatment equipment
• Industrial dryers and curing ovens
• Powder coating ovens and boiler access doors
• High-temperature access panels and inspection doors
• OEM thermal equipment

Kiln and oven considerations
Buyers should specify door dimensions, gasket channel geometry, sealing gap, profile, opening frequency, compression requirement, surface condition and required length. The gasket must be designed to match the door gap and retention system.

Custom cut lengths & manufacturing options
BSTFLEX manufactures wire-jacketed fiberglass gasket material to customer requirements. Supply options include straight cut lengths, equipment-specific lengths, matched gasket sets and OEM quantities. Custom options:

• Gasket diameter and profile dimensions
• Fiberglass construction and internal core selection
• Stainless steel wire mesh outer jacket
• Finished length and end treatment
• Cut-to-length supply, sample development and drawing-based production

Applications summary
Choose the wire-jacketed gasket when high-temperature sealing must be combined with significant mechanical abrasion or frequent door movement. For low-abrasion conditions a conventional fiberglass gasket may suffice.
