# Sanitary clamp spools, 10 and 12 in, 3 and 6 in long (tri-clamp style)

> How is a 10 inch tri-clamp spool built?

- Category: Hardware › Sanitary clamp fittings
- Kind: Standard part
- Basis: Two L14AM7-type ferrule ends on 10.000 / 12.000 in × 0.134 in tube; lengths face to face

**Exact dimensions.** Every file is drawn at true size with no printing tolerance. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your printer's or process's clearance before making the part.

## Notes

- Spools at these sizes are made to order: a length of tube with a ferrule welded on each end. I draw 3 and 6 in face to face; any length is the same drawing with a longer tube.
- The gasket-groove diameter (C2) at 10 and 12 in is not in ISO 2852 (its table stops below these sizes): it is drawn at flange − 7.5 mm, the land width the site already uses for the 4 in, and stated as derived. Everything else here is from the cited tables.

## Questions

**Can I buy a 10 in tri-clamp spool?**

Yes, from a sanitary fabricator, as ferrules welded on a length of 10 in tube; the drawing is the spec.
