Yellow Ring Grey = Flexicarb Solid Green = 316L. Ring Color Coding gaskets are color coded to help expedite the selection and identification of the gaskets you need. The color of the outside edge of the centering ring identifies both the winding and filler materials. The metallic winding filler materials are designated by color stripes at equal intervals on the outside edge of the centering ring.

4 The Flexitallic color code meets the industry standard for metal and filler materials which has been adopted by ASME and the Metallic Gasket division of the Fluid Sealing Association.

5 Flange Face Designs Spiral Wound Gasket Identification 11. Flange Inspection 1. Ensure flange faces are clean and free from imperfections. These could be detrimental to the sealing performance. 2. Carefully remove any solid residue from the flanges, using scrapers, wire brush or cloth.

Such tool marks are practically impossible to seal regardless of the type of Gasket used.

7 Gasket Assembly, Bolting and Compression 15. Bolting Recommendations When utilizing Torque wrenches the use of suitable lubricants on the stud threads and nut bearing faces is recommended, Molybdenum di-sulphide or Nickel powder anti-seize compounds. We recommend a four stage tightening method as follows: 1. Torque the bolts at 30% of the final loading using the appropriate bolt pattern. 2. 60% of final load. 3. 100% of final load. 4. 100% of final torque using a clockwise pattern. 10. 1 5 0. %. 8 3. lts Bo 8- 4 7. 6 2.

Required Gasket Compression for Spiral Wound gaskets Spiral Wound gaskets with internal or external rings, Styles CG'. and CGI' can be compressed to the ring thickness, if necessary. This will not damage the Gasket or affect the sealing performance and the ring is provided as a compression limiting stop. For optimum performance Flexitallic Spiral Wound gaskets should be compressed to these thicknesses. INITIAL Gasket RECOMMENDED COMPRESSED. THICKNESS THICKNESS. mm ( in) mm ( in).
