Product overview
14WF Plain Conical Bevel-Seat Liner Geometry
The 14WF Bevel Seat Plain Short Ferrule is the unthreaded liner half of a sanitary bevel-seat union. Machined from 304L or 316L stainless steel, the fitting features an angled conical bevel face on the union end, a radial retaining collar that captures a 13H hexagonal union nut, and a short butt-weld tangent prepared for sanitary tube welding.
Distinction from 15WF Threaded Ferrules and Union Assembly
In a complete bevel-seat union joint, the 14WF plain ferrule pairs with a 15WF ACME-threaded male ferrule and a 13H hex union nut. Whereas the 15WF ferrule carries external ACME threads and an internal recess, the 14WF ferrule has a smooth outer collar (dimension D from 1.312 inch to 4.593 inch) and a projecting conical nose (dimension E from 1.160 inch to 4.340 inch) that seats against the mating 15WF cone or bevel seat gasket.
Published Inch Dimensions Across 1" to 4" Sizes
The dimensional drawing covers six nominal tube sizes: 1 inch, 1-1/2 inch, 2 inch, 2-1/2 inch, 3 inch, and 4 inch. Weld end outside diameter (C) matches standard inch tube OD from 1.000 inch to 4.000 inch with bore ID (B) from 0.870 inch to 3.834 inch, while overall length (A) progresses from 1.312 inch to 1.750 inch.
Pre-Weld Nut Placement Check
Because the 13H union nut slips over the tube end behind the 14WF shoulder, slide the nut onto the pipe before welding.
