Tri-clamp jacket shell: clamp-on sealed jacket for a 2 in tube — dimension sheet
Source: Xem Studio, https://xemstudio.com/objects/tri-clamp-jacket-shell/  (CC BY 4.0)
Basis: ASME BPE 2 in tube OD (Ø50.8); chamber volume from the drawn geometry
Catalog version: 2026-10-20

Sizes: see table below
- Two halves close on the tube OD in the same place as the finned cooler. Each half is a sealed half-annular chamber: inner wall 2 mm on the tube, chamber 10 mm, outer wall 2 mm, closed ends and a closed split wall, so each half holds its own fill (50.3 mL).
- Each half has one fill port at its top: a Ø6 port through a Ø12 × 4 boss on the outer wall, 8 mm below the top end, closed by the cap (Ø6 spigot). Fill it with the jacket standing as on the engine, port up. The fill is the builder's choice.
- The same four M4 × 30 screws and nuts as the cooler hold the halves on the tube.
