Product overview
Space-Saving End-Cap Reducer Geometry
Unlike long tapered conical reducers (31-14MP), a Tri-Clamp end cap reducer transitions between two clamp sizes within the thickness of a blind cap plus a short ferrule neck. A large Tri-Clover end-cap disc forms the major port, while a smaller concentric Tri-Clamp ferrule projects directly from its center.
Cataloged in both 304L and 316L stainless steel, this compact profile fits tight vessel headers, sight-glass mounts, and instrumentation takeoffs where axial space is restricted.
Seven Listed Reducing Combinations (2" to 4")
The product schedule offers seven imperial size reductions in 304L and 316L: 2" × 1-1/2", 2-1/2" × 1-1/2", 3" × 1", 3" × 1-1/2", 3" × 2", 3-1/2" × 2", and 4" × 1-1/2".
The companion END CAP REDUCER dimensional chart illustrates the major cap diameter, minor ferrule diameter, and compact overall height.
Flow Orientation & Drainability Considerations
Because the internal transition steps abruptly across a flat end-cap shoulder rather than a gradual cone, mounting on horizontal liquid lines can trap residual fluid at the bottom of the larger ferrule.
Use end-cap reducers primarily on vertical runs, top tank nozzles, gas/vapor lines, or compact gauge/sensor ports where minimal build height is the priority.
