Size designations are as printed. The source does not explicitly label the linear-dimension unit; confirm the dimensioned drawing and unit before ordering. Blank or TBC entries are not confirmed values. Movements are separate values; they are not a confirmed simultaneous movement envelope. Flange drilling designation does not establish the rubber assembly pressure-temperature rating.
Specifications compiled from available product documents。Dimensions, performance and suitability are subject to confirmed drawings and ordering documents.
