# Sanitary clamp tees and short-outlet tees (7MP, 7MPS): ½ to 4 in

> What are the dimensions of a 2 inch tri-clamp tee?

- Category: Hardware › Sanitary clamp fittings
- Kind: Standard part
- Basis: ASME BPE / 3-A clamp-fitting dimensions published identically by Dixon and Steel & O'Brien; ISO 2852 face profile
- Page: https://xemstudio.com/objects/sanitary-clamp-tees/ · JSON: https://xemstudio.com/api/geometry?object=sanitary-clamp-tees · Plain text: https://xemstudio.com/objects/sanitary-clamp-tees/sheet.txt

**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

- Equal tee (7MP): a run with a face at each end and one branch of the same size at 90°. Run face to face B, branch centre to face A.
- Short-outlet tee (7MPS): the same run with a branch only as long as its flange needs, for a gauge, probe or valve right at the line; 1 to 4 in.
- Faces are the ISO 2852 profile (2.85 mm rim, 1.6 mm gasket recess, 20° back cone) on the BPE flange diameters; the groove diameter on ½, ¾ and 4 in is derived (flange − 7.0 / 7.5 mm), the rest is from the standard.

## Mating features (exact size; open press / slide / run / socket by your process clearance, leave designed and clamp as drawn)

## Questions

**How long is a 2 inch sanitary clamp tee?**

177.8 mm (7.0 in) face to face on the run, 88.9 mm (3.5 in) centre to branch face.

**What is a short-outlet tee?**

A tee whose branch is only as long as its flange needs: 41.3 mm (1.625 in) centre to face on 2 in, against 88.9 for the equal tee.
