Type "F" Gaskets are made to fit within the bolt hole circle of the flange faces. The outside diameter of the gasket is slightly larger than the inside diameter of the bolt hole circle.

Insulating Sleeves and Washers are available in complete kits, with or without a gasket. Sleeves and washers are available as separate parts or as a one-piece molded unit.

Type "D" Gaskets are made specifically to fit into the ring groove of RTJ flanges. They are available in reinforced phenolic and other materials.

Flange insulation kits are available for all flange sizes, types, pressure ratings and materials. Each kit is individually and securely packed in a reinforced corrugated cardboard box, which is clearly labeled as to its contents for convenience in warehousing and field use.

Sleeves and washers are enclosed in a strong polyethylene bag to eliminate any possibility of loss. A chart showing the recommended sequence for tightening flange bolts is also included with each kit, as well as with each individual gasket. Very large diameter gaskets are packaged separately from the sleeves and washers for convenience in storing and handling.

One 1/8" thick steel washer for each bolt.

Two insulating washer for each bolt.

One full length insulating sleeve for each bolt.

One Type "E" gasket, phenolic retainer/nitrile sealing element.
