# DIN 32676 clamp ferrules, series A (metric), DN10 to DN150

> What are the dimensions of a DIN 32676 DN25 clamp ferrule?

- Category: Hardware › Sanitary clamp fittings
- Kind: Standard part
- Basis: DIN 32676 series A on DIN 11850 tube: tube OD × wall per DIN 11850 series 2; flange and gasket bead per the Rubber Fab chart (its gasket IDs match these bores); ISO 2852 face profile

## Notes

- Metric clamp ferrules for European fittings and equipment: DN10–DN20 share the 34 mm flange, DN25–DN40 the 50.5, DN50 64, DN65 91, DN80 106, DN100 119, DN125 155, DN150 183.
- A 50.5 or 64 mm metric flange mates with the inch clamp of the same flange size; the tube behind it is metric.
- Every clamp face is the ISO 2852 profile used across this site: 2.85 mm rim, flat face with the gasket groove (K 1.6 deep, R3 1.2 bottom, 23° walls, P2 0.8 edges) on C2, 20° back cone. Flange C3 / groove C2 / tube OD × wall, mm: ½–¾ in 25.0 / 20.4 (derived) / 12.7–19.05 × 1.65; 1–1½ in 50.5 / 43.5 / 25.4–38.1 × 1.65; 2 in 64.0 / 56.5 / 50.8 × 1.65; 2½ in 77.5 / 70.5 / 63.5 × 1.65; 3 in 91.0 / 83.5 / 76.2 × 1.65; 4 in 119.0 / 110.0 / 101.6 × 2.11; 6 in 166.9 (6.570 in) / 156.5 / 152.4 × 2.77; 8 in 217.7 (8.570 in) / 207.0 / 203.2 × 2.77; 10 in 268.5 / 261.0 / 254.0 × 3.40; 12 in 319.3 / 311.8 / 304.8 × 3.40.

## Questions

**Does a DIN 32676 DN40 fit a 1½ in tri-clamp?**

Same 50.5 mm flange and clamp, so the joint mates; the tube is 41 × 1.5 instead of 38.1 × 1.65.
