Notes
- A weld ferrule: one ISO 2852 face on a length of BPE tube. Short (14WMP) is 12.7 mm (0.5 in) long, medium (L14AM7) 28.6 mm (1.125 in).
- 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).
- Flange: ½–¾ in share Ø25.0, 1–1½ in share Ø50.5, 2 in Ø64.0, 2½ in Ø77.5, 3 in Ø91.0, 4 in Ø119.0.
- 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.
