Product overview
Ferrule structure and model dimensions
The 14WMP ferrule combines a clamp sealing flange and a short weld neck. Its title designates 12.7 mm length. The shared dimension chart lists 14WMP, 14MMP and 14AMP D-length columns separately: use the 14WMP column, retaining blank cells and printed alternatives. Bore, weld-tube diameter and clamp-flange diameter describe different mating dimensions.
Which dimensions identify this ferrule?
Specify the tube outside diameter, bore, clamp-flange outside diameter and axial length separately. Match the end form and sealing face to the actual mating parts; a shared flange diameter alone does not establish interchangeability.
How do the model drawing and configuration labels relate?
The drawing separates A (bore), B (weld-tube OD), C (flange OD) and model-specific D (length). Use the column for this model. Linear units are not stated on the retained drawing; confirm them before manufacture. Existing configuration labels such as 25, 38 or 51 mm are retained as supplied and are not a verified rounding or cross-reference to the drawing’s 25.4, 38.1 or 50.8 values.
