Revision of F3347-23 Standard Specification for Metal Press Insert Fittings with Factory Assembled Stainless Steel Press Sleeve for SDR9 Cross-linked Polyethylene (PEX) Tubing and SDR9 Polyethylene of Raised Temperature (PE-RT) Tubing
Rationale
To resolve the dimensional conflicts in Table 1, several adjustments are required: T Min specified is greater than calculated Min Thickness from the allowable diameters. So, make dimension 'B' to be 'Bmin' with the following values: 0.165” for 5/16”, 0.232” for 3/8”, 0.358” for ½”, 0.453” for 5/8”, 0.555” for ¾”, 0.722” for 1”, 0.898” for 1.25”, 1.075” for 1.5”, and 1.405” for 2”. Update dimension 'A' for the 1-1/2” size to 1.232”. Update dimension 'D' for the 1-1/2” size to 1.205”. Update dimension 'C' for the 2” size to 10° - 20°. Update dimension 'L' for the 2” size to 1.05”. Update dimension 'Tmin' for the 1-1/4” size to 0.051”. Update dimension 'Tmin' for the 1-1/2” size to 0.055”.
