Source: Xem Studio, https://xemstudio.com/objects/sanitary-clamp-gaskets/  (CC BY 4.0)
Basis: ISO 2852 Type B profile (bead 5.5, web 1.7, lip 1.1 × ±2.8) on each size; OD = flange − 1, lip ID = bore − 2.2
Catalog version: 2026-10-20

Sizes: see table below
- The Type B gasket for each size: a 5.5 mm bead that fills both face recesses, a 1.7 mm web on the lands, and a 1.1 mm inner lip standing 2.8 mm each side of the centre plane.
- OD = flange − 1 mm; bead out to the groove diameter − 0.4 mm; lip ID = bore − 2.2 mm. Each file is drawn for its tube size (the ½ and ¾ in gaskets differ only in lip ID).
- The 1.5 and 2 in gaskets on the tri-clamp gasket page have the same profile with the bead out to the groove diameter itself.
