Sanitary clamp crosses (9MP): ½ to 4 in
What are the dimensions of a 2 inch tri-clamp cross? · Standard part · basis: ASME BPE / 3-A clamp-fitting dimensions published identically by Dixon and Steel & O'Brien; ISO 2852 face profile
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. Mating features

Notes
- A cross (9MP): a run with two opposite branches of the same size, four faces in all. Run face to face B, each branch centre to face A.
- From ¾ in up the cross has the same run and branch lengths as the equal tee of that size; the ½ in cross is longer (114.3 run, 57.1 branch) than the ½ in tee.
- 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.
