# Sanitary clamp tees, short-outlet tees and crosses, ½ to 4 in (tri-clamp style, BPE)

> 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 two manufacturers; ISO 2852 face profile; drawn by Xem Studio from those numbers
- Page: https://xemstudio.com/objects/sanitary-clamp-tees-crosses/ · JSON: https://xemstudio.com/api/geometry?object=sanitary-clamp-tees-crosses · Plain text: https://xemstudio.com/objects/sanitary-clamp-tees-crosses/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): run face to face B, branch centre to face A. Short-outlet tee (7MPS): same run, branch only as long as the flange needs, for an instrument or a sample valve close to the line. Cross (9MP): run and two opposite branches.
- Faces: ISO 2852 profile (2.85 mm rim, 1.6 mm gasket recess, 20° back cone) on the BPE flange diameters ½–¾ in 25.0, 1–1½ in 50.5, 2 in 64.0, 2½ in 77.5, 3 in 91.0, 4 in 119.0 mm; tube OD 12.7 / 19.05 / 25.4 / 38.1 / 50.8 / 63.5 / 76.2 / 101.6 mm, wall 1.65 mm (4 in: 2.11). The gasket-groove diameter on ½, ¾ and 4 in is derived (flange − 7.0 / 7.5 mm, the land width of every size ISO 2852 lists); the rest is from the standard.

## Questions

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

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

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

A port right at the line for a gauge, thermowell or sample valve: the branch is just long enough for the flange (2 in: 1.625 in centre to face).
