Sanitary clamp tees, short-outlet tees and crosses, ½ to 4 in (tri-clamp style, BPE) — dimension sheet
Source: Xem Studio, https://xemstudio.com/objects/sanitary-clamp-tees-crosses/  (CC BY 4.0)
Basis: ASME BPE / 3-A clamp-fitting dimensions published identically by two manufacturers; ISO 2852 face profile; drawn by Xem Studio from those numbers
Catalog version: 2026-10-20

Sizes: see table below
- 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.
