Compressed fiber (non-asbestos) is the high-temperature, high-pressure workhorse for rigid flange and exhaust sealing. Where elastomers soften or burn, fiber holds a tight seal against heat, steam, and bolt load. We laser-cut custom fiber gaskets to your exact dimensions with no minimum order and ship within one business day. Custom Fiber Gasket Specifications Temperature range Up to 500°F+ (higher than standard elastomers) Construction Compressed non-asbestos fiber — rigid, not elastic Excellent resistance to High heat, high bolt pressure, steam, oils, and many chemicals Poor resistance to Applications needing elasticity or low-torque conformity Thicknesses available 1/16", 1/8", 3/16", 1/4" Additional specifications and specific durometers are available on request — contact us with your requirements. Common Fiber Gasket Applications Exhaust and header flange gaskets High-pressure pipe and flange seals Steam and boiler equipment Industrial pump and valve gaskets Compressor and manifold seals Chemical process flanges When to Choose Fiber Choose Fiber for high-temperature and high-pressure flange service where rubber would soften, burn, or blow out. For low-clamp-load or flexible sealing, choose Cork or an elastomer such as EPDM or Neoprene instead. Fiber Gasket FAQs What is compressed fiber gasket material?Compressed non-asbestos fiber is a rigid gasket material that withstands high temperatures and bolt pressures, used for exhaust, steam, and high-pressure flange sealing.How much heat can fiber gaskets take?Compressed fiber handles 500°F and beyond — well above standard elastomers — making it the choice for exhaust and boiler flanges.Is fiber gasket material flexible?No. Fiber is rigid, not elastic. For applications that need a soft, conforming seal at low bolt load, choose Cork or a rubber elastomer.
