GRAFOIL is pure graphite.No fillers or no binders, nothing to leach out or harden. It is free from corrosion, embrittlement and aging.The gaskets and packing made from Grafoil can perform successfully even under extreme conditions.

• They can withstand from -200⁰ C to 1850⁰ C or as high as 3000⁰ C in the absence of oxygen.
• They are resistant to all aggressive media such as highly concentrated acids, solvents and hot oils.
• They are resilient across entire temperature range of any length of time.
• They are not susceptible to cold or hot flow at the highest permitted surface pressure.
• They are unaffected by radiation and are recommended for use in nuclear plants.
• They are permitted to use in conjunction with oxygen.
• They are physiologically inert.
• Flange distortions are compensated.
• Advantages :

  Grafoil is available in a variety of forms for versatile maintenance and OEM applications.

• As endless or split gland packing rings and self sealing rings.

Bush bearings in different grades of carbon (resin or antimony impregnated) with or without housing in different sizes are offered depending on the requirement. Segmented carbon rings with SS garter spring for any size are available with different joint configurations.

We feel proud to introduce ourselves as the leading organization in this domain, engaged in presenting an excellent grade of Mechanical Seals. At our manufacturing unit, our professionals use quality stainless steel materials of high grade and modern technology for manufacturing these seals. Professionals also adhere to industry standards for while manufacturing the offered seals. These seals can stand out temperature in-between -40C to 140C sustaining 20 bar pressure. Mostly, these seals are found suitable for Sumo pump shaft having 12 mm and 16 mm size.
