NON-METALLIC GASKET MATERIAL

Teadit North America Logo

Non-metallic gasket material, or sheet gasket, is available in a wide array of materials to suit numerous applications. STS Industrial stocks gasket material, and cuts standard and custom gaskets in house. The basic types of non-metallic gasket material are Non-Asbestos, Rubber, PTFE, and Flexible Graphite.

There are two main designs when it comes to flange gaskets cut from non-metallic sheet gasket:

  • Ring gaskets are a flat sealing element, consisting of an inner and outer diameter sized to fit a flange’s bore and bolt circle. Ring gaskets sit inside the flange’s bolt circle. ASME B16.2 and ASME B16.47 govern the dimensions of ring gaskets for standard and large diameter pipe flanges.
  • Full Face gaskets are a flat sealing element, consisting of an inner and outer diameter, and a specified number of bolt holes, the center of which are evenly spaced around a bolt circle. Full face gaskets are designed to fill the entire space between flat-faced flanges, with bolt holes that match the size and arrangement of the bolt holes in the intended flanges. ASME B16.2 and ASME B16.47 govern the dimensions of full face gaskets for standard and large diameter pipe flanges.

  • Teadit Quimflex SH PTFE Sheet

    Quimflex SH (24SH) 100% Expanded PTFE

    Quimflex SH gasket sheet is manufactured by expanding 100% virgin PTFE using a proprietary process that produces a uniform and highly fibrillated microstructure with equal tensile strength in all directions. The resulting product exhibits characteristics significantly different than conventional PTFE sheet. This style is much softer and more flexible than regular PTFE sheet and thus conforms easily to irregular and rough surfaces. In addition, the material is easier to compress and minimizes creep and cold flow. Teadir 24SH gasket material complies to FDA regulations for food contact and EU 1935/2004. Quimflex SH is an all purpose gasket sheet that can replace all other types of PTFE sheet. It will seal all aggressive chemicals over the entire 0-14 pH range except for molten alkali metals and elemental fluorine. Made from 100% virgin PTFE, it not only resists chemical attack, but it will not contaminate or discolor end products.

  • Teadit Graflex flexible graphite sheet has pressure-temperature sealability capabilities that are far superior to all asbestos reinforced and non-asbestos reinforced sheet products. It is resistant to chemical attack by virtually all organic and inorganic fluids with the exception of concentrated, highly oxidizing acids. Gaskets cut from flexible graphite sheet seal with low to moderate bolt loads and because of very low creep relaxation, re-torquing is rarely required. Flexible graphite conforms to irregular flange sealing surfaces and readily flows into flange irregularities enabling it to seal both smooth and coarse surface finishes.

    Graflex 2660/1660 Homogeneous Flexible Graphite

    Style 2660/1660  flexible graphite sheet is made from exfoliated graphite flake which is compressed into foil by a carefully controlled calendering process. In this process, the expanded flake particles are mechanically locked together without the use of fibers, binders or other additives. Sheets of foil are then adhesive bonded and laminated to the required thickness.
