24、er O-Ring gasket consists of a solid toroid of rubber which is contained within the grooves of a pair of flange fac- ings according to the series of EN 1092 and which seals the flanges due to a combination of compression of the gasket and the deformation imposed on the gasket by the retained fluid 3

26、sizes) Gasket nominal sizes shall be designated in accordance with the ranges specified in Table 1. 4.3 Information to be supplied by the purchaser The selection of polymer type from which required O-Ring gaskets are to be made should take into account the fluid and the operating conditions. It is r
27、ecommended that selection of a gasket for any particular application is made in con- sultation with the gasket supplier who will advise on the materials required for a particular service (see annex A). When ordering gaskets the nominal diameter and the PN number shall be given and, after discussion
28、as required with the manufacturer, the polymer type.
