AIFILTECH High-Temperature Sealing Rings & Gaskets

Temp rating 500~1000 C
Recovery High
Eco Asbestos-free

Product Introduction

High-temperature sealing rings are made from reinforced ceramic fiber, graphite or mica, rated 500-1000 C with good recovery and reliable sealing for kilns, burners, flanges and exhaust piping.

Detailed Overview

01 Product Overview

Sealing rings are die-cut, wound or metal-frame reinforced from ceramic fiber paper/blanket, flexible graphite or mica sheet, in rectangular, O-ring or V-ring sections. High compression recovery compensates for flange unevenness and thermal deformation; no harmful volatiles, no brittleness or shedding at temperature.

02 Performance & Mechanism

Preload deforms the porous fiber or graphite material elasto-plastically to fill surface asperities. The material stays resilient at temperature, continuously compensating for gaps caused by thermal cycling and delivering long-term low-leakage sealing.

03 Advantages

  • Continuous rating 500-1000 C, short-term higher; 2. High recovery compensates thermal deformation; 3. Low chlorine and sulfur, non-corrosive to flange faces; 4. Full size range, custom sizes to drawing; 5. Asbestos-free and environmentally compliant.

04 Applications

Static sealing for kiln flanges, burner connections, exhaust flanges, hot air ducts and valve bonnets. Standard sizes ex-stock plus custom production to drawing.

Applications

Kiln flanges Burners Exhaust piping Custom
