Teadit 24Sh Full Face Gasket

Teadit 24Sh Full Face Gasket
Manufacturers:
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 B16.21 and ASME B16.47 govern the dimensions of full face gaskets for standard and large diameter pipe flanges. TEADIT 24SH is a large gasket sheet produced from 100% pure, multi-directionally expanded PTFE. Universally employable gasket sheet for all applications. It is suitable for all types of flanges, nearly all media, a wide temperature range and for applications with the toughest demands on purity. It is inherently clean and non-toxic. Gaskets of multi-directionally expanded PTFE have exceptional mechanical strength which allows operation with minimal creep at elevated temperatures. The excellent malleability of TEADIT 24SH makes repairing small damage and/or irregularities of the sealing area (flange surface) unnecessary. Gaskets cut from TEADIT 24SH are dimensionally stable, i. e. they do not get wider when compressed. This allows narrow flange faces to be sealed safely. TEADIT 24SH is quick and simple to install. The used gasket can be removed easily and without residue.
