Notes
- The Type B gasket between two ISO 2852 faces: a 5.5 mm bead that fills both face recesses, a 1.7 mm web on the lands, and an inner lip into the bore.
- 2 in: OD Ø63.0, bead out to Ø56.5 (the groove diameter), lip ID Ø45.3. 1.5 in: OD Ø49.5, bead to Ø43.5, lip ID Ø32.6. The lip is 1.1 mm thick radially and stands 2.8 mm each side of the centre plane (5.6 overall).
- The sanitary-clamp gasket page carries the same profile for every size ½ to 4 in, with the bead 0.2 mm inside the groove diameter on radius.
