Tri-clamp spool (two ferrules on a tube), 1.5 and 2 inch
What are the face-to-face lengths and volumes of 1.5 and 2 inch tri-clamp spools? · Hardware · basis: ISO 2852 faces on ASME BPE 16 ga tube; catalog lengths
- sizes
- 7 in table
Notes
- Face-to-face length is the spool's stated length. Internal volume sets a thermoacoustic engine's resonance; volumes assume 16 ga tube.
- 2 in bore: 50.8 − 2×1.65 = 47.5 mm → 17.7 cm³ per cm. 1.5 in: 34.8 mm → 9.5 cm³ per cm.
- Stack-up per joint: two faces + one compressed gasket web ≈ 2.1 mm (ISO 2852 V). A clamp adds about 10 mm of radial envelope beyond the flange.
- The files carry the full ISO 2852 face, so a printed spool mates with a printed cap and a real clamp for mock-ups.

Questions
What is the internal volume of a 2 inch tri clamp spool?
About 17.7 cm³ per cm of length with 16 ga tube (47.5 mm bore): a 6 in spool is roughly 270 cm³, a 12 in spool 540 cm³ before the ferrule faces.
What is the bore of a 1.5 inch tri clamp spool?
34.8 mm (38.1 mm OD tube, 1.65 mm wall), about 9.5 cm³ per cm.
How long is a tri clamp joint stack-up?
Two ferrule faces plus one compressed gasket web, about 2.1 mm per joint (ISO 2852 V). A clamp adds roughly 10 mm of radial envelope beyond the flange.
