DIPTI METAL INDUSTRIES
Compressed Non-Asbestos Fiber (CNAF) Gaskets: Unrivaled Sealing Performance
Dipti Metal – Your Trusted Global Partner for Reliable, Safe, and High-Performance Industrial Sealing Solutions.
🏭 About Dipti Metal Industries
At Dipti Metal Industries, we proudly stand as a premier manufacturer, exporter, and supplier of superior quality Compressed Non-Asbestos Fiber (CNAF) Gaskets. Recognized globally as a modern, safe, and exceptionally effective alternative to hazardous asbestos-based materials, our CNAF gaskets are meticulously engineered to deliver exceptional sealing performance across the most rigorous and diverse industrial applications. We are committed to providing reliable industrial gasket solutions that meet stringent safety and environmental regulations.
Our advanced CNAF gaskets are precisely fabricated from an expertly curated blend of high-strength aramid fibers, inert inorganic fillers, and premium elastomeric binders such as NBR (Nitrile Butadiene Rubber), SBR (Styrene Butadiene Rubber), or EPDM (Ethylene Propylene Diene Monomer). This sophisticated mixture is then subjected to high pressure and elevated temperatures, resulting in dense, homogenous, and structurally sound sheets. This cutting-edge composition guarantees superior mechanical strength, remarkable thermal stability, and outstanding chemical resistance, positioning our CNAF gaskets as the preferred choice for critical and demanding flange sealing requirements in process piping and equipment.

If your country is not listed, we can still arrange shipments worldwide from Indian ports (JNPT, Mundra, Chennai, etc.).
Key Features and Benefits of Our CNAF Gaskets
- Asbestos-Free & Environmentally Safe: Adhering strictly to international safety standards, our non-asbestos gaskets provide a completely safe and compliant sealing solution, eliminating health risks associated with older materials.
- Broad Chemical Compatibility: Engineered for versatility, our gaskets exhibit robust resistance to an extensive array of aggressive media, including hot water, high-pressure steam, various oils, fuels, mild acids, alkalis, and many industrial chemicals, ensuring durable and reliable sealing in diverse chemical environments.
- Excellent Thermal Stability: Our CNAF grades are formulated to maintain sealing integrity across a wide and challenging temperature spectrum, preventing leaks due to thermal cycling.
- High Pressure Resistance & Blow-out Protection: Built to withstand substantial and fluctuating system pressures, these high-pressure gaskets offer exceptional blow-out resistance, ensuring pipeline integrity and operational safety even under extreme loads.
- Superior Conformability & Recovery: Optimized composition provides excellent seating characteristics, conforming to minor flange irregularities and delivering a tight seal with remarkable recovery after pressure/temperature variations, contributing to low creep and stress relaxation.
- Cost-Effective & Durable: Reduces maintenance frequency and downtime, offering long-term value.
- Anti-Stick Properties: Many grades feature good anti-stick characteristics for easier disassembly and replacement.
- Note: Actual limits depend on sheet grade, media, and joint design. Share your operating data for an exact recommendation.
