Product overview
Short-Pattern Coaxial Transition Construction
Designed for compact process manifolds, vessel ports, and skid headers where standard-length concentric reducers exceed available axial space, this short-pattern fitting joins a 3-inch or 4-inch Tri-Clamp ferrule directly to a 1-1/2-inch Tri-Clover ferrule along a single central axis. Both variants are manufactured in 304L low-carbon stainless steel under supplier part codes F1RCTC4030015S and F1RCTC4040015S.
Tabulated Dimensions for Both Short Configurations
The drawing chart defines three primary envelope dimensions: overall face-to-face length A, large-end ferrule flange outside diameter B, and small-end ferrule flange outside diameter C. Because the conical transition occurs over a shortened axial span, the cone angle is steeper than that of a standard-length reducer.
• 3" x 1-1/2" Short (SKU F1RCTC4030015S): overall length A = 2.750", large ferrule OD B = 3.582", small ferrule OD C = 1.988".
• 4" x 1-1/2" Short (SKU F1RCTC4040015S): overall length A = 4.125", large ferrule OD B = 4.685", small ferrule OD C = 1.988".
Clamp Clearance and Gasket Selection
On short-pattern reducers, the steep conical wall sits close to the back of both ferrule flanges. Installers should check that heavy-duty hinged clamps and wing nuts can swing and seat freely around the 3.582-inch or 4.685-inch large flange and the 1.988-inch small flange without contacting the tapered body.
Procurement and Engineering Notes
Wall thickness, internal bore diameters, surface roughness Ra, and pressure-temperature ratings are not printed on the source sheet. Confirm internal bore alignment with mating 3-inch, 4-inch, and 1-1/2-inch sanitary gaskets before installation.
